[PATCH 1/2] drm/amd/pm: Add debug prints

[Luben Tuikov]

Add prints where there are none and none are printed in the callee.

Add a print in sienna_cichlid_run_btc() to help debug and to mirror other
platforms, as no print is present in the caller, smu_smc_hw_setup().

Remove the word "previous" from comment and print to make it shorter and
avoid confusion in various prints.
