Moving of_init_opp_table from mach-imx6q.c to imx6q-cpufreq.c in order to avoid adding it to mach-imx6sl.c.
    Just incase the cpu frequency scaling is enabled on iMX6SL.

Drop the leading spaces and wrap the lines around 72 column.

For this patch, a proper patch subject prefix would be 'cpufreq: imx6q: '
You can use 'git log' to find out what a proper prefix for a file/patch
should be.

Before doing that in the driver, you should check and make sure that
platform hasn't supply a opp table.

Ahh ok I think I got what you mean here..

I should call opp_get_opp_count(cpu_dev) to check if the platform
supplied it. If not, call the of_init_opp_table.
