gpio: aspeed: fix compile testing warning
Gcc cannot always see that BUG_ON(1) is guaranteed to not
return, so we get a warning message in some configurations:
drivers/gpio/gpio-aspeed.c: In function 'bank_reg':
drivers/gpio/gpio-aspeed.c:244:1: error: control reaches end of non-void function [-Werror=return-type]
Using a plain BUG() is easier here and avoids the problem.
Fixes: 44ddf559d579 ("gpio: aspeed: Rework register type accessors")
