The UARTs on the MPC824x are unique devices and really shouldn't be thought
of as a DUART.  In addition, if both UARTs are in use we need to configure
the part to enable the 2nd UART since the pins for the UARTs are
multiplexed.  Adds support to run the 824x Sandpoint with both UARTs if
desired.

This patch adds the Freescale MPC86xADS board support.  The supported
devices are SMC UART and 10Mbit ethernet on SCC1.

The manual for the board says that it "is compatible with the MPC8xxFADS
for software point of view".  That's why this patch extends FADS instead of
introducing a new platform.

FEC is not supported as the "combined FCC/FEC ethernet driver" driver by
Pantelis Antoniou should replace the current FEC driver.

The MPC8548 has 48 internal interrupts and 12 external interrupts.  The
previous generation PowerQUICC III devices only had 32 internal and 12
external interrupts on the primary interrupt controller.

Expanded the number of internal interrupts to 48 for all PowerQUICC III
processors and moved the interrupt numbers for the external after the 48
internal interrupt lines, rather than putting the 12 new internal
interrupts at the end and ifdef'ng the whole mess.  As parted of this
created a macro which represents the internal interrupt senses since they
are the same on all PQ3 processors.

Despite all the care lately in making the powermac sleep/wakeup as
robust as possible, there is still a nasty related to the use of cpufreq
on PMU based machines.  Unfortunately, it affects paulus old powerbook
so I have to fix it :)

We didn't manage to understand what is precisely going on, it leads to
memory corruption and might have to do with RAM not beeing properly
refreshed when a cpufreq transition is done right before the sleep.

The best workaround (and less intrusive at this point) we could come up
with is included in this patch.  We basically do _not_ force a switch to
high speed on suspend anymore (that is what is causing the problem) on
those machines.  We still force a speed switch on wakeup (since we don't
know what speed we are coming back from sleep at, and that seems to work
fine).

Since, during this short interval, the actual CPU speed might be
incorrect, we also hack around by multiplying loops_per_jiffy by 2 (max
speed factor on those machines) during early wakeup stage to make sure
udelay's during that time aren't too short.

For after 2.6.12, we'll change udelay implementation to use the CPU
timebase (which is always constant) instead like we do on ppc64 and thus
get rid of all those problems.

Recent kernels occasionally trigger a PMU timeout on some mac laptops,
typically on wakeup from sleep.  This seem to be caused by either a too big
latency caused by the cpufreq switch on wakeup from sleep or by an
interrupt beeing lost due to the reset of the interrupt controller done
during wakeup.

This patch makes that code more robust by stopping PMU auto poll activity
around cpufreq changes on machines that use the PMU for such changes (long
latency switching involving a CPU hard reset and flush of all caches) and
by removing the reset of the open pic interrupt controller on wakeup (that
can cause the loss of an interrupt and Darwin doesn't do it, so it must not
be necessary).

Some G3 CPUs can crash in funny way if a store from an FPU register
