scsi: ufs: ufs-pci: Remove UFS PCI driver's ->late_init() call back

->late_init() was introduced to allow the default values for rpm_lvl and
spm_lvl to be set.  Since commit bb9850704c04 ("scsi: ufs: core: Honor
runtime/system PM levels if set by host controller drivers") and commit
fe06b7c07f3f ("scsi: ufs: core: Set default runtime/system PM levels
before ufshcd_hba_init()"), those default values can be set in the
->init() variant call back.

Move the setting of default values for rpm_lvl and spm_lvl to ->init()
and remove ->late_init().
