[PATCH AUTOSEL 5.19 23/33] cpufreq: check only freq_table in __resolve_freq()

[Sasha Levin <sashal@kernel.org>]

From: Lukasz Luba <lukasz.luba@arm.com>

[ Upstream commit 6ca7076fbfaeccce173aeab832d76b9e49e1034b ]

There is no need to check if the cpufreq driver implements callback
cpufreq_driver::target_index. The logic in the __resolve_freq uses
the frequency table available in the policy. It doesn't matter if the
driver provides 'target_index' or 'target' callback. It just has to
populate the 'policy->freq_table'.

Thus, check only frequency table during the frequency resolving call.
