scsi: ufs: core: Do not look for unsupported vdd-hba-max-microamp

Bindings do not allow vdd-hba-max-microamp property and the driver does not
use it (does not control load of vdd-hba supply).  Skip looking for this
property to avoid misleading dmesg messages:

  ufshcd-qcom 1d84000.ufs: ufshcd_populate_vreg: unable to find vdd-hba-max-microamp
