scsi: ufs: ufs-pci: Fix default runtime and system PM levels

Intel MTL-like host controllers support auto-hibernate.  Using
auto-hibernate with manual (driver initiated) hibernate produces more
complex operation.  For example, the host controller will have to exit
auto-hibernate simply to allow the driver to enter hibernate state
manually.  That is not recommended.

The default rpm_lvl and spm_lvl is 3, which includes manual hibernate.

Change the default values to 2, which does not.

Note, to be simpler to backport to stable kernels, utilize the UFS PCI
driver's ->late_init() call back.  Recent commits have made it possible
to set up a controller-specific default in the regular ->init() call
back, but not all stable kernels have those changes.
