usb: typec: qcom: Update the logic of regulator enable and disable

Browse Source 
Removed the call logic of disable and enable regulator
in reset function. Enable the regulator in qcom_pmic_typec_start
function and disable it in qcom_pmic_typec_stop function to
avoid unbalanced regulator disable warnings.
