drm/xe/xe2_hpg: Correct implementation of Wa_16025250150
Wa_16025250150 asks us to set five register fields of the register to
0x1 each. However we were just OR'ing this into the existing register
value (which has a default of 0x4 for each nibble-sized field) resulting
in final field values of 0x5 instead of the desired 0x1. Correct the
RTP programming (use FIELD_SET instead of SET) to ensure each field is
assigned to exactly the value we want.
