realtek: convert access to RTL931x "digital 1" serdes pages
The RTL931x has 14 frontend and at least 26 backend serdes. Currently
the programming functions always need to determine the right backend
serdes from the given frontend serdes on their own. We plan to provide
a consistent serdes mapping to all callers.
As the second step make use of these new functions whenever we
want to access the digital 1 pages. The pages are mapped starting
at 0x100. So the function conversion is as simple as this:
Old:
dsds = (sds - 1) * 2;
rtmdio_931x_read_sds_phy(dsds, page, ...)
New:
rtmdio_931x_read_sds_phy_new(sds, page + 0x100, ...)
