net: phy: micrel: fix KSZ8081/KSZ8091 cable test

Commit 21b688dabecb ("net: phy: micrel: Cable Diag feature for lan8814
phy") introduced cable_test support for the LAN8814 that reuses parts of
the KSZ886x logic and introduced the cable_diag_reg and pair_mask
parameters to account for differences between those chips.

However, it did not update the ksz8081_type struct, so those members are
now 0, causing no pairs to be tested in ksz886x_cable_test_get_status
and ksz886x_cable_test_wait_for_completion to poll the wrong register
for the affected PHYs (Basic Control/Reset, which is 0 in normal
operation) and exit immediately.

Fix this by setting both struct members accordingly.
