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
