scsi: ufs: Prepare to add HCI capabilities sysfs

Prepare so we'll be able to read various other HCI registers.  While at it,
fix the HCPID & HCMID register names to stand for what they really are.
Also replace the pm_runtime_{get/put}_sync() calls in auto_hibern8_show to
ufshcd_rpm_{get/put}_sync() as any host controller register reads should.
