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.
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).
