ufs: enhancements to support Qualcomm UFS controllers
This serie regroups all the fixes and base enhancements required to
support the Qualcomm UFS controllers in U-Boot.
This syncs headers & defines from Linux, and includes 2 set of
fixes that were sent separately:
- ufs: core: remove link_startup_again logic
- ufs: properly fix cache operations
Without those 2 sets, UFS cannot initialize on Qualcomm controlers
since v5, and a numerous of Cache issues makes any UFS controller
fail to initialize.
Since UFS core hasn't changed for a while, and since UFS is core
technology for the Qualcomm SoCs, I volunteer maintaininig the
UFS subsystem if Bhupesh & Neha Malcom Francis are ok with that.
