realtek: pcs: rtl93xx: enable 100BASE-X support

Browse Source 
The generic, RTL930x, and RTL931x setup paths now handle 100BASE-X.
Add the RTL93xx hardware mode value and mapping, select the 1G analog
CMU page, and advertise the mode from RTL93xx SerDes instances.

This makes the prepared support available to PCS consumers.
