drm/xe/xe_guc_ads: Add nonpriv registers to write list

When performing a guc_mmio_regset_write, we add all the registers in the
reg_sr list to the save/restore list, but do not do the same for the
nonpriv registers.  Add them in.

v2:
- Add all NONPRIV registers to avoid undefined behavior (Harrison)
- s/whitelist/nonpriv

v3:
- Rebase
