MMC1 is the only MMC interface available on the platform. Further, since the platform is based on older revision of SoC which is not capable of doing multi-block reads, mark it with compatibility for the same and add pinmux to ensure that all relevant pins are configured for non-MMC boot mode. Signed-off-by: Nishanth Menon <nm@ti.com> --- Changes since V1: - fixed commit message as suggested by Balaji. - update to use new compatible match for the erratum.
