To cover additional host controller programming mentioned in the UFS specification we have added an additional protocol
that allows the UEFI driver to give control to platform driver. This allows the platform to perform any additional
steps needed for the stable operation.

Changes in v2:
- UFS driver will abort initializaton when it fails to get host controler information
- Fixed bug with calling post link startup callback on failed device detection

Test coverage:
Tested on platform with UFS 2.1 host controller with Samsung UFS2.0 part with 3 LUs enabled All LUs have been enumerated in boot manager.
Tested that enumeration works without platform protocol installed(on host controller that can support it) Tested that enumeration works with platform protocol installed and with additional programming steps after link startup(power mode change to GEAR2).
