The following are driver and documentation patches to enable UHS modes for
TI's AM65x, J721e, and J7200 boards. Device tree and defconfig patches
will be sent in a separate series.

With the complete set, the following maximum modes will be supported:

am654x-evm,idk		- SDR104, HS200
j721e-common-proc-board	- DDR50, HS200
j7200-common-proc-board	- DDR50, HS200

These patches mainly add support for the software tuning algorithm[1]
needed for higher speed modes
