Remove the PCI retry timeout code, for all the same reasons that
Luis Rodriguez removed it for ath9k.

The MIB interrupt fires whenever counters overflow; however without
support for automatic noise immunity, we can sometimes get an interrupt
storm. The get_stats() callback reads the counters anyway so we can
disable the interrupt for now until ANI is implemented. This fixes
the issue reported in http://bugzilla.kernel.org/show_bug.cgi?id=12647.

* Convert chip specific calibration data to a generic format common
for all chips
Note: We scale up power to be in 0.25dB units for all chips for
compatibility with RF5112

* Fix a typo in initvals.c so that we use the RF2425 array for RF2425 and not RF2413
Note: This also fixes incorect pd gain overlap since RF2425 has different pd gain overlap from RF2413

Radiotap was updated to include a "bad PLCP" flag and standardise
the "bad FCS" flag in the "flags" rather than "RX flags" field,
this patch updates Linux to that standard.

AP mode currently sets up the dual stream capability
for all stations. This patch fixes it by checking if the
associated station supports dual stream MCS rates (8-15).
We would disregard any MCS rates above 15, since Atheros
HW supports only 0..15 rates currently, and can't receive
at rates > 15 anyway.

Remove the PCI retry timeout code as that was just taken from ipw2100
due to historical reasons but in reality its a no-op, additionally its
simply incorrect as each PCI devices has its own custom PCI configuration
space on PCI config space >= 0x40. Not to mention we were trying to write
0 to a place that already has 0 on it.

When there are no free snums, UCC ethernet should gracefully fail, but
currently it oopses this way:
# ifconfig eth0 up
fill_init_enet_entries: Can not get SNUM.
ucc_geth_startup: Can not fill p_init_enet_param_shadow.
eth0: Cannot configure net device, aborting.

[efb25df0] [c020eec0] dev_open+0xc0/0x118
[...]
This is because the ucc_geth_stop() routine assumes that ugeth->phydev
is always initialized by the ucc_geth_open(), while it is not in case
of errors.
If we add a check to the ucc_geth_stop(), then another oops pops up:
Unable to handle kernel paging request for data at address 0x00000004
Faulting instruction address: 0xc01b46a4
Oops: Kernel access of bad area, sig: 11 [#1]

[ef83bff0] [c000f464] kernel_thread+0x4c/0x68
[...]
That one happens because ucc_geth_stop() does not call phy_disconnect()
and so phylib state machine is running without any idea that a MAC has
just died.
Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY
is disabled, we'll get this oops:
0:01 not found
eth2: Could not attach to PHY
eth2: Cannot initialize PHY, aborting.

[...]
And again, ucc_geth_stop() assumes that ugeth->phydev is there, while
it isn't.
This patch fixes all three oopses simply by rearranging some code:
- In ucc_geth_open(): move init_phy() call to the beginning, so
that we only call ucc_geth_stop() with a PHY attached;
- Move phy_disconnect() call from ucc_geth_close() to
ucc_geth_stop(), so that we'll always disconnect the PHY.

DMA mapping can be expensive in the presence of iommus.
Reduce the Rx iommu activity by mapping an entire page, and provide the H/W
the mapped address + offset of the current page chunk.
Reserve bits at the end of the page to track mapping references, so the page
can be unmapped.
