gpio: aspeed: avoid return type warning

[ Upstream commit 11e299de3aced4ea23a9fb1fef6c983c8d516302 ]

gcc has a hard time tracking whether BUG_ON(1) ends
execution or not:

drivers/gpio/gpio-aspeed-sgpio.c: In function 'bank_reg':
drivers/gpio/gpio-aspeed-sgpio.c:112:1: error: control reaches end of non-void function [-Werror=return-type]

Use the simpler BUG() that gcc knows cannot continue.
