mmc: sdhci_omap: Fix TI SoC dependencies

[ Upstream commit 09f164d393a6671e5ff8342ba6b3cb7fe3f20208 ]

The sdhci_omap is specific to  older TI SoCs, update the
dependencies for those SoCs and compile testing. While we're
at it update the text to reflect the wider range of
supported TI SoCS the driver now supports.
