[ Upstream commit 8bad3bf23cbc40abe1d24cec08a114df6facf858 ]
When current CPU load is not L0 then loading armada-37xx-cpufreq.ko driver fails with following error:
# modprobe armada-37xx-cpufreq [ 502.702097] Unsupported CPU frequency 250 MHz
This issue was partially fixed by commit 8db82563451f ("cpufreq: armada-37xx: fix frequency calculation for opp"), but only for calculating CPU frequency for opp.
Fix this also for determination of base CPU frequency.
