Magnus Damm 9b7c23adb3 ARM: mach-shmobile: Use 0x2200 as INTCS_VECT_BASE
Change INTCS_VECT_BASE from 0x3400 to 0x2200.

The old value 0x3400 gave the INTCA and INTCS interrupt
conrollers separated spaces, but required ARM support
for more than 512 NR_IRQS which is not in place at this
point.

The value 0x2200 will make some of the INTCA interrupts
make use of empty INTCS areas. This is a bit more error
prone but works fine as a workaround for G3, G3 and AP4.
