msm: camera: utils: revert to Add support for cesta hw client voting through mmrm

Browse Source 
Currently, cesta hw client rates are being set through mmrm, camera
passes clk rate required and voting happens on mmrm side. This reverts that
funtionality and allows camera to use qcom_clk_crm api to vote directly
in util layer without passing to mmrm.
