Armada A38x implements an SDHCI compatible SDIO controller. This patch enables the Marvell driver to support this SoC. And enables the SDIO controller if selected by the board configuration. Tested on Marvell DB-88F6820-GP board. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Pantelis Antoniou <panto@antoniou-consulting.com> Cc: Luka Perkov <luka.perkov@sartura.hr>
