====================
Add TJA1120 support

This patch series got bigger than I expected. It cleans up the
next-c45-tja11xx driver and adds support for the TJA1120(1000BaseT1
automotive phy).

Master/slave custom implementation was replaced with the generic
implementation (genphy_c45_config_aneg/genphy_c45_read_status).

The TJA1120 and TJA1103 are a bit different when it comes to the PTP
interface. The timestamp read procedure was changed, some addresses were
changed and some bits were moved from one register to another. Adding
TJA1120 support was tricky, and I tried not to duplicate the code. If
something looks too hacky to you, I am open to suggestions.
