realtek: simplify SoC detection

Browse source 
Read model name from the register instead of using hard-coded values.

Also remove detection of the unsupported Realtek ESW/SSW SoCs. The Fast
Ethernet variants of the Maple and Cypress series stay for now, but are
moved to the RTL8380/RTL8390 families.
