Subject: [PATCH 41/41] Documentation: ARM: Document new dependencies for MMC on DRA7

MMC on DRA7 SoCs require different IO Delay values to be configured
depending on the MMC mode. In order to confgiure these IO Delay values
CONFIG_PINCTRL_TI_IODELAY must be enabled. Document this dependency
here so that it can be added by anyone using custom .config.
