[PATCH net-next v2 2/4] net: phy: add registers to support 1000BASE-T1

[Stefan Eichenberger <eichest@gmail.com>]

Add registers and definitions to support 1000BASE-T1. This includes the
PCS Control and Status registers (3.2304 and 3.2305) as well as some
missing bits on the PMA/PMD extended ability register (1.18) and PMA/PMD
CTRL (1.2100) register.
