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 v3:
- 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).

For the 3rd patch, in order to please the PatchCheck.py, I will change the
title a little bit to:
* MdeModulePkg/UfsPassThruDxe: Refactor private data to use UfsHcInfo

Other than that, for the series,
Reviewed-by: Hao A Wu <hao.a.wu@intel.com>

Since there is already a confirmation from Laszlo for adding this feature in
the upcoming stable tag:
https://edk2.groups.io/g/devel/message/45217?p=,,,20,0,0,0::Created,,ufs,20,2,0,32784353

I plan to push the series tomorrow (after around 24 hours, in case if there
are additional feedbacks).

Best Regards,
Hao Wu
