mmc: omap_hsmmc: Fix pbias for omap3_logic to enable CD pin

Browse Source 
The MMC card detect pin is connected to gpio127 on omap3_logic.
When setting up the pbias register for MMC, let's also enable
gpio_127 for the card detect.  As part of the package deal,
gpio_126 and gpio_129 are also enabled.
