There is no problem for drivers to request pll_m and pll_p clocks for
the device, hence there is no need to use clk_get_sys() and it could be
replaced with devm_clk_get() for consistency.

Interesting... I didn't know that clk_get() had a fallback path to
return clk_get_sys() if the named clock wasn't found in DT. That's
nice.

Looks good to me.

Yes, I didn't know either until recently. Thanks!
