Some code in existing drivers checked return value to be equal to 0 or less/equal to 0 which is also wrong because phandle_t is unsigned type. Most of these checks were for negative cases that were never triggered so trhere was no impact on functionality.

This is done by changing the PLL multiplier, and cannot be done if any core is in doze or sleep mode.
