MMC1 also needs "ti,needs-special-hs-handling" dt property to indicate support
for properly supporting SD HS cards.

mmc: omap_hsmmc: Enable HSPE bit for high speed cards
HSMMC IP on AM33xx need a special setting to handle High-speed cards.
Other platforms like TI81xx, OMAP4 may need this as-well. This depends
on the HSMMC IP timing closure done for the high speed cards.
