regulator: cpr-regulator: remove SVS CPR quotient constraints

Remove the target quotient validation check which requires the
nominal corner target quotient to be strictly greater than the
SVS corner target quotient. This check unnecessarily disables
CPR on targets which have an SVS quotient that is programmed to
be equal to the nominal quotient.
