Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency.  While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board.  The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.

Before we can send a command we need both the DATI (command inhibit on
mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear.
The previous behavior of only checking on DATI was insufficient on some
cards and incorrect behavior in any case.  This makes the code check
for both bits being clear and makes the error print more clear as
to what happened.  DATI_CMDDIS is removed as it was unused elsewhere
in the code and stood for 'DATI is set, cmds are disabled still'.

Fix originally spotted by Peter Bigot.

OMAP boards currently use a legacy mmc driver. This patch adds a new
mmc driver which will work with the generic mmc driver in u-boot.

This new driver will work with both OMAP3 and OMAP4 boards.

This patch does not remove the old driver.  It should remain in the
tree until all boards that use it switch to the new driver.

This patch adds support for the second and third mmc channels on OMAP3
processors

Boards wishing to use this feature should define CONFIG_SYS_MMC_SET_DEV
in the board config

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
