realtek: rtl931x: Fix SDS field modifications

Browse Source 
A RTL930x function to read the value from an SDS register must not used on
an RTL931x SoC. Doing it with rtl930x_read_sds_phy() would corrupt the
written results when only parts of the bits are written.

Fixes: 7026084066 ("realtek: Add SDS configuration routines for the RTL93XX platforms")
