regulator: bd71837: Disable voltage monitoring for LDO3/4
There is a HW quirk in BD71837. The shutdown sequence timings for bucks/LDOs which are enabled via register interface are changed. At PMIC poweroff the voltage for BUCK6/7 is cut immediately at the beginning of shut-down sequence. This causes LDO5/6 voltage monitoring to detect under voltage and force PMIC to emergency state instead of poweroff. Disable voltage monitoring for LDO5 and LDO6 at probe to avoid this.
