PM / OPP: Move error message to debug level
[ Upstream commit 035ed07208dc501d023873447113f3f178592156 ]
On some i.MX6 platforms which do not have speed grading
check, opp table will not be created in platform code,
so cpufreq driver prints the following error message:
cpu cpu0: dev_pm_opp_get_opp_count: OPP table not found (-19)
However, this is not really an error in this case because the
imx6q-cpufreq driver first calls dev_pm_opp_get_opp_count()
and if it fails, it means that platform code does not provide
OPP and then dev_pm_opp_of_add_table() will be called.
In order to avoid such confusing error message, move it to
debug level.
It is up to the caller of dev_pm_opp_get_opp_count() to check its
return value and decide if it will print an error or not.
