From: David Laight <david.laight.linux@gmail.com>
Rather than use a define that should be internal to the implementation
of FIELD_PREP(), pass the shifted 'val' to nfp_eth_set_bit_config()
and change the test for 'value unchanged' to match.
This is a simpler change than the one used to avoid calling both
FIELD_GET() and FIELD_PREP() with non-constant mask values.
