net: ll_temac: Add support for non-native register endianness
Replace the powerpc specific MMIO register access functions with the
generic big-endian mmio access functions, and add support for
little-endian access depending on configuration.
Big-endian access is maintained as the default, but little-endian can
be configured in device-tree binding or in platform data.
The temac_ior()/temac_iow() functions are replaced with macro wrappers
to avoid modifying existing code more than necessary.
