[ Upstream commit 92963903a8e11b9576eb7249f8e81eefa93b6f96 ]

Commit 8db82563451f ("cpufreq: armada-37xx: fix frequency calculation for
opp") changed calculation of frequency passed to the dev_pm_opp_add()
function call. But the code for dev_pm_opp_remove() function call was not
updated, so the driver cleanup phase does not work when registration fails.

This fixes the issue by using the same frequency in both calls.
