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 writes, mark it so and add pinmux
to ensure that all relevant pins are configured for non-MMC boot
mode.

ti,erratum-2.1.1.128 introduced in https://patchwork.kernel.org/patch/3514851/
hence depends on the same.
