pwm: pwm-mediatek: Beautify error messages text

As a cherry-on-top cleanup, make error messages clearer to read
by changing instances of "clock: XXXX failed" to a more readable
"Failed to get XXXX clock". Also add "of" to unsupported period
error.

This is purely a cosmetic change; no "real" functional changes.
