Subject: [PATCH v2 1/1] mmc: dw_mmc: hi3798cv200: add MMC_CAP_CMD23 cap

Enable access to the RPMB on the on-board eMMC of the
Poplar board.

Signed-off-by: Igor Opaniuk <igor.opaniuk@...aro.org>

v2:
- as there are three dwmmc blocks integrated on Hi3798CV200 SoC with
identical CMD23 support, provide MMC_CAP_CMD23 capability instead of 0 for 
the third block also.
