[PATCH net-next v9 03/15] ax88179_178a: Fix endianness of pause watermark register

[Birger Koblitz <mail@birger-koblitz.de>]

The 16-bit pause watermark register is little endian as
described in the ASIX 4.1.0 out-of-tree driver. Correct the
register byte sequence but also swap the configuration values
used in the code in order to keep the current behaviour.

The endianness is relevant for 16-bit writes to the register.
