Increase the max number of GPIOs from default 512 to 1024 for ASPEED
platforms, because Facebook Yamp (AST2500) BMC platform has total 594
GPIO pins (232 provided by ASPEED SoC, and 362 by I/O Expanders).

Thanks Linus for the review. I will add ARM SoC and SoC maintaniers in
patch v2.
Somehow get_maintainer.pl doesn't list the 2 addresses in my tree; do I
need to send a patch to update MAINTAINERS accordingly?
