Add support for 1000BASE-T1 to the phy-c45 helper and add a first
1000BASE-T1 driver for the Marvell 88Q2110 PHY.

v3:
  - Read the BASE-T1 capabilities from the ability register (Andrew)
  - Fix several missing return values (Francesco)
  - Poll the reset bit to be sure the soft reset was done (Andrew)
  - Fix reading the latched link status wrongly (Andrew/Russell)
  - Remove probe function (Francesco)
  - Add defines for Marvell specific registers (Andrew)
  - Move the BASE-T1 ability reading to a separate function (Andrew)

v2:
 - Use the same pattern in Kconfig as for 88X2222 (Andrew)
 - Sort Kconfig and Makefile entries (Andrew)
 - Add generic registers to mdio.h (Andrew)
 - Move generic functionality to phy-c45.c (Andrew)
 - Document where proprietary registers are used (Andrew)
 - Remove unnecessary c45 check (Andrew)
 - Remove cable tests which were not implemented (Andrew)
 - Remove comma for terminator entry (Francesco)
 - Sort include files (Francesco)
 - Return phy_write_mmd value in soft_reset (Francesco)
