Enable 8-bit host capability for HSMMC2 and/or HSMMC3. CONFIG_HSMMC2_8BIT (for OMAP4/5/DRA7xx) and/or CONFIG_HSMMC3_8BIT (for DRA7xx only) must be defined in the board header if an 8-bit eMMC device is connected to the corresponding port. Fix the "No status update" error that appeared for eMMC devices by inserting a 20 us delay between writing arguments and command. This solution has been proposed by Michael Cashwell <mboards@prograde.net>. A minor cosmetic fix in a comment as well. Signed-off-by: NLubomir Popov <lpopov@mm-sol.com>
