realtek: pcs: rtl93xx: make cmu_page getter generic

Browse Source 
Rename rtpcs_931x_sds_cmu_page_get() to rtpcs_93xx_sds_get_cmu_page()
and move it next to the other 93xx-shared helpers, so RTL930X can
reuse it instead of duplicating the same hw_mode-to-CMU-page switch.
Also fix the wrong -ENOTSUPP return to -EOPNOTSUPP.
