[ARM] VIC: Update asm/hardware/vic.h with PL192 information
The original arch/arm/include/asm/hardware/vic.h was written for the PL190 ARM VIC implementation, and as such does not have any information about the PL192 version. Add details about the PL192 and PL190 specific registers and any changes between the two units. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
