Subject: [PATCH net-next v3 0/3] net: enetc: remove bootloader dependency

These patches were picked from the following series:
https://lore.kernel.org/netdev/1567779344-30965-1-git-send-email-claudiu.manoil@nxp.com/
They have never been resent. I've picked them up, addressed Andrews
comments, fixed some more bugs and asked Claudiu if I can keep their SOB
tags; he agreed. I've tested this on our board which happens to have a
bootloader which doesn't do the enetc setup in all cases. Though, only
SGMII mode was tested.

changes since v2:
 - removed SOBs from "net: enetc: Initialize SerDes for SGMII and USXGMII
   protocols" because almost everything has changed.
 - get a phy_device for the internal PCS PHY so we can use the phy_
   functions instead of raw mdiobus writes
 - reuse macros already defined in fsl_mdio.h, move missing bits from
   felix to fsl_mdio.h, because they share the same PCS PHY building
   block
 - added 2500BaseX mode (based on felix init routine)
 - changed xgmii mode to usxgmii mode, because it is actually USXGMII and
   felix does the same.
 - fixed devad, which is 0x1f (MMD_VEND2)

changes since v1:
 - mdiobus id is '"imdio-%s", dev_name(dev)' because the plain dev_name()
   is used by the emdio.
 - use mdiobus_write() instead of imdio->write(imdio, ..), since this is
   already a full featured mdiobus
 - set phy_mask to ~0 to avoid scanning the bus
 - use phy_interface_mode_is_rgmii(phy_mode) to also include the RGMII
   modes with pad delays.
 - move enetc_imdio_init() to enetc_pf.c, there shouldn't be any other
   users, should it?
 - renamed serdes to SerDes
 - printing the error code of mdiobus_register() in the error path
 - call mdiobus_unregister() on _remove()
 - call devm_mdiobus_free() if mdiobus_register() fails, since an
   error is not fatal
