Subject: [PATCH] cpufreq: sun50i: fix error returns in dt_has_supported_hw()

The dt_has_supported_hw() function returns type bool.  That means these
negative error codes are cast to true but the function should return
false instead.

Fixes: fa5aec9561cf ("cpufreq: sun50i: Add support for opp_supported_hw")
