Krzysztof Kozlowski 0f5796dac1 cpufreq: dt-platdev: Fix creating device on OPPv1 platforms 
Commit 6ea891a6dd ("cpufreq: dt-platdev: Simplify with
of_machine_get_match_data()") broke several platforms which did not have
OPPv2 proprety, because it incorrectly checked for device match data
after first matching from "allowlist".  Almost all of "allowlist" match
entries do not have match data and it is expected to create platform
device for them with empty data.

Fix this by first checking if platform is on the allowlist with
of_machine_device_match() and only then taking the match data.  This
duplicates the number of checks (we match against the allowlist twice),
but makes the code here much smaller.
