Starfive JH8100 SoC consists of a Cadence SD/eMMC host controller
(Version 6) with Combo PHY which provides DFI interface to SD/eMMC
removable or embedded devices. This patch adds initial SD/eMMC support
for JH8100 SoC by providing device drivers for Cadence SD/eMMC Version 6
host controller and Combo PHY.  This patch series is depending on the
JH8100 base patch series in [1], [2], and [3].
The relevant dt-bindings documentation has been updated accordingly.
