hw/char/pl011: Mark implementation as being little-endian

The PL011 component is only built / used by ARM targets, which
are only built in little endianness. Thus we only ever built
as little endian, never testing the big-endian possibility of
the DEVICE_NATIVE_ENDIAN definition. Simplify by only keeping
the little endian variant.
