sunxi: Fix PHY regression on A20-OLinuXino-Lime2 and A20-Olimex-SOM-EVB

When moving the PHYLIB PHY drivers around in Kconfig we did not at the
same time perform a careful migration of the related drivers and
sub-options.  This lead to the case where previously Kconfig-enabled
driver choices were now disabled on some platforms.  Correct this by
enabling both the PHY driver and sub-option on the above referenced
platforms.

Fixes: af2cbfd6 ("drivers: net: Provide Kconfig menu for PHYLIB")
Fixes: 8728c97e ("configs: Re-sync")

After checking back on the original commit I can see that these are the
only two platforms to have been broken in the change.
