net: remove empty MDIO bus reset functions

This patchset removes all empty MDIO bus reset functions that we have in the
tree (hopefully all of them). This function is optional for the MDIO bus code in
drivers/net/phy/mdio_bus.c::mdiobus_register, the documentation is updated to
reflect that.

Having less call sites to update will allow us to implement a generic BMCR_RESET
based PHY reset for MDIO buses that require to reset their PHYs before their
PHY detection succeeds (e.g: HiSilicon hip04 current submission) and provide it
as a helper.
