[PATCH] irqchip: GICv3: ITS: don't assume 64K page size in its_alloc_tables

[stuart.yoder@freescale.com (Stuart Yoder)]

its_alloc_tables() needs to account for page sizes other than
64KB.  Without this change, when PAGE_SIZE=4KB its_alloc_tables()
gets stuck in an infinite loop.

think this should go into 4.1 if at all possible...without it I am
unable to boot a 4.1 kernel on the LS2085 SoC
