The rtl8211f supports downshift and before commit 5502b218e001
("net: phy: use phy_resolve_aneg_linkmode in genphy_read_status")
the read-back of register MII_CTRL1000 was used to detect the
negotiated link speed.
The code added in commit d445dff2df60 ("net: phy: realtek: read
actual speed to detect downshift") is working fine also for this
phy and it's trivial re-using it to restore the downshift
detection on rtl8211f.
Add the phy specific read_status() pointing to the existing
function rtlgen_read_status().

V1 => V2
move from a generic implementation affecting every phy
to a rtl8211f specific implementation
V2 => V3
rebase on netdev-next, resolving minor conflict after
merge of 8b43357fff61
