Subject: [PATCH v2 1/2] dt-bindings: mmc: add Marvell ac5

From: Elad Nachman <enachman@...vell.com>

Add dt bindings for Marvell AC5/X/IM eMMC controller.
This compatibility string covers the differences in the
AC5/X version of the driver: 31-bit bus limitation and
DDR memory starting at address 0x2_0000_0000, which are handled
by usage of a bounce buffer plus a different DMA mask.
