Implement basic part of SA-1110/SA-1100

Browse source 
Basic implementation of DEC/Intel SA-1100/SA-1110 chips emulation.
Implemented:
 - IRQs
 - GPIO
 - PPC
 - RTC
 - UARTs (no IrDA/etc.)
 - OST reused from pxa25x

Everything else is TODO (esp. PM/idle/sleep!) - see the todo in the
hw/strongarm.c
