platform/x86: apple-gmux: don't use be32_to_cpu and cpu_to_be32
Sparce doesn't seem to like using be32_to_cpu and cpu_to_be32 to convert
values for the MMIO gmux to/from the host architecture.
Instead use iowrite32be and ioread32be to always convert, which should be
fine because apple-gmux is only used on x86 with is always little endian.
