Fix the __iomem annotation of the iomem_base pointers in the apple-gmux
code. The __iomem should go before the *.
This fixes a bunch of sparse warnings like this one:
drivers/platform/x86/apple-gmux.c:224:48: sparse:
expected void const [noderef] __iomem *
got unsigned char [usertype] *
Fixes: 0c18184de990 ("platform/x86: apple-gmux: support MMIO gmux on T2 Macs")
