Remove the temporary @mask_, this may cause build warning when use clang
compiler for powerpc, but can't reproduce it when compile for arm64.
the build warning is caused by:
"warning: result of comparison of constant 18446744073709551615 with
expression of type (aka 'unsigned long') is always false
[-Wtautological-constant-out-of-range-compare]"
More information provided in below lore link.
After removing @mask_, there is a "CHECK:MACRO_ARG_REUSE" when run
checkpatch.pl, but due to @mask is constant, no reuse problem will happen.

Change the inline function mtk_phy_update_field() into a macro to
avoid check warning of FIELD_PREP() with compiler parameter
-Wtautological-constant-out-of-range-compare
the warning is caused by mask check:
"BUILD_BUG_ON_MSG(__bf_cast_unsigned(_mask, _mask) > \"

Due to FIELD_PREP() macro can be used to prepare a bitfield value,
local ones can be remove; add the new helper to make bitfield update
easier.
