[ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into one
This makes the code better organized and simplified a bit. The change
will lose a bit of performance when performing IRQ ack/mask/unmask,but
that's not too much after checking the result binary.
This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by
carefully not to access those pxa{27x,3xx} specific registers, this
is done by keeping an internal IRQ number variable. The pxa-regs.h
is also modified so registers for IRQ > PXA_IRQ(31) are made public
even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake)
The incorrect assumption in the original code that internal irq starts
from 0 is also corrected by comparing with PXA_IRQ(0).
"struct sys_device" for the IRQ are reduced into one single device on
pxa{27x,3xx}.
