net/wan/fsl_ucc_hdlc: fix reading of __be16 registers
When releasing the allocated muram resource, we rely on reading back
the offsets from the riptr/tiptr registers. But those registers are
__be16 (and we indeed write them using iowrite16be), so we can't just
read them back with a normal C dereference.
This is not currently a real problem, since for now the driver is
PPC32-only. But it will soon be allowed to be used on arm and arm64 as
well.
