Add eMMC support for k3-am654-idk in a linux inmate cell using
ENABLE_INMATE_CELL_EMMC macro, and respective device tree changes
Signed-off-by: Matt Ranostay <mranos...@ti.com>
---
Changes from v1:
* Split out eMMC enablement to its own inmate configuration
Changes from v2:
* Recombined eMMC enablement to one configuration that is enabled
with ENABLE_INMATE_CELL_EMMC define
* Dropped patches that were already merged
