Subject: [PATCH 1/5] net: phy: realtek: support interrupt also for C22
 variants

Now that access to MDIO_MMD_VEND2 works transparently also in Clause-22
mode, add interrupt support also for the C22 variants of the
RTL8221B-VB-CG and RTL8221B-VM-CG. This results in the C22 and C45
driver instances now having all the same features implemented.
