[PATCH V2 2/2] ARM: dts: omap3-ldp: fix mmc configuration

[Nishanth Menon]

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.

Changes since V1:
	- fixed commit message as suggested by Balaji.
	- update to use new compatible match for the erratum.
