Most boards use 25000000 as the default HZ, so rather than add a whole
bunch more boards, make it the default for everyone.  This also fixes
randconfig builds as there was no default before.

Before we configure the early UART, check to make sure we are running on

When a low priority interrupt (like ethernet) is triggered between 2 high
priority IPI messages, a deadlock in disable_irq() is hit by the second
IPI handler.  This is because the second IPI message is queued within the
first IPI handler, but the handler doesn't process all messages, and new
ones are inserted rather than appended.  So now we process all the pending
messages, and append new ones to the pending list.

git commit 0a0c5168 "PM: Introduce functions for suspending and resuming

functions are only available for architectures which support
GENERIC_HARDIRQS.

Other architectures will see this build error:

drivers/built-in.o: In function `device_power_down':
