1e39b224b6 net: mdio: octeon: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

93641ecbaa net: mdio: cavium: Separate C22 and C45 transactions
The cavium IP can perform both C22 and C45 transfers.  Create separate
functions for each and register the C45 versions in both the octeon
and thunder bus driver.

e1d027dd97 net: mdio: octeon: Fix some double free issues
'bus->mii_bus' has been allocated with 'devm_mdiobus_alloc_size()' in the
probe function. So it must not be freed explicitly or there will be a
double free.

Remove the incorrect 'mdiobus_free' in the error handling path of the
probe function and in remove function.

a9770eac51 net: mdio: Move MDIO drivers into a new subdirectory
Move all the MDIO drivers and multiplexers into drivers/net/mdio.  The
mdio core is however left in the phy directory, due to mutual
dependencies between the MDIO core and the PHY core.

Take this opportunity to sort the Kconfig based on the menuconfig
strings, and move the multiplexers to the end with a separating
comment.
