net: phy: Realtek RTL8211B/C PHY ID fix
The RTL8211B_driver structure in drivers/net/phy/realtek.c contains a
wrong PHY ID (0x1cc910 instead of 0x1cc912) in the uid field.
The lowest four bits of the PHY ID encode the chip revision (B+C/D/E/F)
of the RTL8211 and the code originally applied a mask of 0xfffff0 to
the PHY ID, so that matching the PHY ID to the appropriate driver code
was only done on the chip type (RTL8211), but not on a specific
revision.
After introduction of support for the RTL8211E, which needed another
startup function than the older chip revisions, commit
42205047674d7fc9e0aa747273fbc7dcfbac3183 changed the mask to 0xffffff
to make the chip revision relevant for the match, but didn't provide
the now-relevant lower bits of the uid field for the RTL8211B/C.
Fix this by setting the full PHY ID in the RTL8211B_driver uid field.
