Subject: [PATCH] ARM: ASPEED: update default ARCH_NR_GPIO for ARCH_ASPEED

From: Tao Ren <rentao.bupt@...il.com>

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).
