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).

EDKII_UFS_HC_PLATFORM_PROTOCOL will allow the platform to inject
platform specific logic into standard UFS flows. Right now we
support callbacks pre and post host controller enable and pre
and post link startup. We also allow the platform to override
host controller capabilities and version which might be usefull
to manage silicon bugs or allow testing experimental features
from new version of the specification.

https://bugzilla.tianocore.org/show_bug.cgi?id=1343
This commit adds EDKII_UFS_HC_PLATFORM_PROTOCOL implementation
in UfsPassThruDxe driver in version 1. Driver assumes that at
most one instance of the protocol exists in the system. Presence
of the protocol is not mandatory.

Hi,
Please ignore this series. I have used wrong branch when generating patches. V3 will contain the fixes.

> with 3 LUs enabled All LUs have been enumerated in boot manager.
> Tested that enumeration works without platform protocol installed(on host
