phy: mediatek: fix build warning of FIELD_PREP()
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) > \"
