net: rswitch: Fold MPSM C45 setting into rswitch_mii_access_c45()

The Set Station Management Mode : Clause 45 setting of MFF bit in MPSM
register can be done in rswitch_mii_access_c45() once, instead of this
being done before each rswitch_mii_access_c45() call. Deduplicate the
bit setting into rswitch_mii_access_c45(). No functional change.
