gpio: amd-fch: Fix type error found by sparse
Sparse complains:
gpio-amd-fch.c:45:27: sparse: expected void *
gpio-amd-fch.c:45:27: sparse: got void [noderef] <asn:2> *
gpio-amd-fch.c:45:27: sparse: warning: incorrect type in return
expression (different address spaces)
gpio-amd-fch.c:56:9: sparse: expected void const volatile [noderef]
<asn:2> *addr
gpio-amd-fch.c:56:9: sparse: expected void volatile [noderef] <asn:2> *addr
gpio-amd-fch.c:56:9: sparse: got void *ptr
gpio-amd-fch.c:56:9: sparse: warning: incorrect type in argument 1 (different address spaces)
I think it is because void * is returned rather than void __iomem *,
so fix it up.
