Subject: [PATCH v2] ARM: dts: rv1108: enable eMMC support

Enable eMMC support for rv1108.dtsi as it can be used across multiple
boards.

Signed-off-by: Otavio Salvador <otavio@...ystems.com.br>

Changes in v2:
- rework evb device tree (Heiko Stuebner)
- avoid adding the evb use as it is not present on evb but
  minievb (which I don't have to test) and we are using it on a custom
  customer board.
