This series adds RMII interface support for the Microchip PCI11x1x
Ethernet controller.

The PCI11x1x device supports RMII as an alternative MAC-PHY interface,
selected via the STRAP_READ software strap register. Patch 1 reads the
RMII strap bits from this register and sets the is_rmii_en flag. Patch 2
uses this flag to configure the PHY interface mode, phylink supported
interfaces, and enables RMII in hardware via the RMII_CTL register.

Change Log:
===========
v2 -> v3:
  - Update debug log to report selected interface (SGMII/RMII/RGMII)
    instead of only SGMII enable/disable state [patch 1/2]
  - Update commit message to document that EEE is disabled by setting
    lpi_capabilities = 0 [patch 2/2]

v1 -> v2:
  - Remove redundant mac_capabilities &= ~MAC_1000FD; phylink already
    handles capability reduction for RMII via phy_caps_from_interface()
    [patch 2/2]
