Pretty much every subtype does this now anyways, and as we depend on it in a
few places being set to something sensible quite early on, it's better for a
new subtype to simply set a sensible default.

A few trivial updates for the microdev board support code:
- Update for __IO_PREFIX changes.
- Consolidate headers into a single microdev.h.
- Update the microdev_defconfig.
- Add init values for the S1D13806 used by s1d13xxxfb.

Avoid lost tick compensation early in boot before the TSCs are
synchronized. Currently timekeeping is enabled before the TSCs are
synchronized, thus when the TSCs are synched (reset to zero), it appears
that a number of lost ticks have occurred. This can cause premature expiry
of timers and in extreme cases can cause the soft lockup detection to fire.
This resolves issues reported by Andy Whitcroft as well as bug #5366
reported by Tim Mann.

Older pSeries systems with serial ports dont get any console output after
recent changes. CONFIG_ISA does not make sense for CONFIG_PPC_PSERIES
because it enables lots of old drivers. Instead, remove the dependency on
CONFIG_ISA from the serial port discovery code.

arch/ia64/sn/Makefile sets CPPFLAGS, expecting that setting to
propogate to all the subdirectories. For a normal build with its
recursive descent it does work, but doing a selective build like
'make arch/ia64/sn/kernel/io_init.i' does not do a recursive descent,
it goes directly to arch/ia64/sn/kernel/Makefile so the flags do not
get set.
To support selective builds, set the flags in all the subordinate Makefiles.

On my latest laptop, I've had occasional PHY dead on wakeup from
sleep... the PHY would be totally unresponsive even to toggling the hard
reset line until the machine is powered down... Looking closely at the
code, I found some possible issues in the way we setup the MDIO lines
during suspend along with slight divergences from what Darwin does when
resetting it that may explain the problem. That patch change these and
the problem appear to be gone for me at least... I also fixed an mdelay
-> msleep while I was at it to the pmac feature code that is called
when toggling the PHY reset line since sungem doesn't call it in an
atomic context anymore.

Add enough arch-specific compat signals code to enable parisc64
to compile and boot out of the mainline tree. There are likely still
many dragons here, but this is a start to squashing the last
big difference between the mainline tree and the parisc-linux tree.
The remaining bugs can be squashed as they come up.

Define a chassis_power_off routine that machines which have a way
to turn off the power supply can hook into. Formerly they were
using pm_power_off, which is now being used by generic code. Make
lasi.c use chassis_power_off instead of pm_power_off.
Note, all machines need to call machine_power_off so that the
switch can power off the machine, though halt -p may not necessarily
be able to work properly on the machine.
