realtek: pcs: rtl931x: adjust SerDes page numbers

Adjust the SerDes page numbers to account for the different mapping used
by 'mdio-realtek-otto' and 'mdio-realtek-otto-serdes' drivers.

While importing the SerDes configuration code from PHY driver to PCS
driver, all helper calls to access the SerDes registers had to be
adjusted to use the proper helpers within the PCS driver. However, there
is one important implication of this: 'mdio-realtek-otto' and
'mdio-realtek-otto-serdes' use a slightly different page mapping.

While the old helpers in 'mdio-realtek-otto' used a page mapping of
0x00/0x100/0x200, 'mdio-realtek-otto-serdes' uses a mapping of
0x00/0x40/0x80 to provide consumers with the ability to only operate on
frontend SerDes. Thus, all page numbers > 63/0x3f have to be adjusted
like the following:

before: rtsds_931x_write_field(sds, 0x101, ...	// old helper calls
after: rtpcs_sds_write(ctrl, sds, 0x41, ...
