net: stmmac: mdio: update runtime PM

Commit 3c7826d0 ("net: stmmac: Separate C22 and C45 transactions
for xgmac") missed a change that happened in commit e2d0acd4
("net: stmmac: using pm_runtime_resume_and_get instead of
pm_runtime_get_sync").

Update the two clause 45 functions that didn't get switched to
pm_runtime_resume_and_get().
