net: rswitch: Add PHY C22 access support
Implement C22 PHY access support in addition to C45 PHY access
support which is already present. This is used for PHYs which
do not support C45 access or which are C22 only.
The C22 access can be recognized when devad is set to -1 or
0xffffffff hex, which also matches MDIO_DEVAD_NONE macro. Test
for this special devad value and if it is set this way, perform
C22 access, otherwise perform C45 access.
