Instead of having a local function taking care of sending the tuning
command, let's use the common mmc_send_tuning() API provided by the mmc
core. In this way the request will be handled as any other request by
sdhci core.
As an effect of this change, the pm_runtime_get_sync() call at
esdhc_prepare_tuning() isn't needed any more.
This patch will also introduce another change in behavior, since before
the response pattern to the tuning command wasn't verified by
sdhci-esdhc-imx. The mmc_send_tuning() does that.

The handling of can error states is different between platforms.
This is an attempt to correct that problem.
I've moved this handling into a generic function for changing the
error state. This ensures that error state changes are handled
the same way everywhere (where this function is used).
This new mechanism also adds reverse state transitioning in error
frames, i.e. the user will be notified through the socket interface
when the state goes down.

Several can modules in drivers/net/can use a banner[] variable at the
top which defines a string that is used once during init. This string
is also embedded with KERN_INFO which makes it printk() specific.
Improve the code by eliminating the banner[] variable and moving the
string to where it is printed. Then switch from printk(KERN_INFO to
pr_info() for the lines that were changed.
This patch is similar to [1] which was applied to net/can.

Getting the pf_id from the function number was a good place to start,
but when the PF was setup in passthru mode, the PCI bus/device/function
was virtualized and the number in the VM is different from the number in
the bare metal. This caused HW configuration issues when the wrong pf_id
was used to set up the HMC and other structures. The PF_FUNC_RID register
has the real bus/device/function information as configured by the BIOS,
so use that for a better number. This works in NPAR mode as well.

All VSIs on a VEB should either have loopback enabled or disabled, a
mixed mode is not supported for a VEB. Since our driver supports multiple
VSIs per PF that need to talk to each other make sure to enable Loopback
for the PF and FDIR VSI as well.
Also, we now have to explicitly enable Loopback mode otherwise we fail
VSI creation for VMDq and VF VSIs.

When multiple VFs attempt to initialize simultaneously, the firmware may
delay or drop messages. Make the init code more adept at handling these
situations by a) reinitializing the admin queue if the firmware fails to
process a request, and b) resending a request if the PF doesn't answer.
Once the request has been sent again, the PF might end up getting both
requests and send the configuration information to the driver twice.
This will cause the VF to complain about receiving an unexpected message
from the PF. Since this is not fatal, reduce the warning level of the
log messages that are generated in response to this event.

Resolve an issue related to images with multiple PFs per physical
port. We cannot fully support 1588 PTP features, since only one port
should control (ie: write) the registers at a time. Doing so can cause
interference of functionality.
It may be possible to partially implement the API for only those
features without side effects. However, this at minimum means non
controlling PFs lose Tx timestamps, frequency atunement, and possibly
SYSTIME adjustment. There may be further impact I did not discover.
Since the API in the kernel expects these features to work, it is
simpler and less dangerous to just disable PTP features on all PFs not
identified as the controlling PF in PRTTSYN_CTL0.PF_ID.
This change also removes the warning printed when hwtstaml IOCTL is
called on the wrong PF. This is actually meaningless now, since only one
PF per port will support it. In addition, the ethtool get_ts_info IOCTL
was updated so that only the controlling port will even indicate support
(so as not to confuse users).
The overall downside is complete loss of functionality on non
controlling PF, vs the possible gain of partial support. The biggest
factor for choosing this approach is simplicity and ensuring that the
main PF will work. There could easily be other portions of the 1588
logic with side effects I am not aware, and the reduced functionality
that might be made available is significantly less useful. In addition,
the API does not allow for proper indication of why particular features
are not supported. These reasons are enough to decide for the simpler
approach to resolving this issue.

In sky2_change_mtu setting B0_IMSK to 0 may be delayed due to PCI write posting
which could result in irqs being still active when synchronize_irq is called.
Since we are not prepared to handle any further irqs after synchronize_irq
(our resources are freed after that) force the write by a consecutive read from
the same register.
Similar situation in sky2_all_down: Here we disabled irqs by a write to B0_IMSK
