scsi: ufs: Update VCCQ2 and VCCQ min/max voltage hard codes

Browse source 
Per UFS 3.0 JEDEC standard, the VCCQ2 min voltage is 1.7v and the VCCQ
voltage range is 1.14v ~ 1.26v. Update their hard codes accordingly to make
sure they work in a safe range compliant for ver 1.0/1.1/2.0/2.1/3.0 UFS
devices.
