When splitting platform data of omap mmc/hsmmc driver it will
allow to check which hwomod uses easily by looking at which header is
included

- mmci driver supports multiple slots, omap_hsmmc only one
this leads to one of the major confusions in the omap_hsmmc driver
- platform data should be read-only for the driver
most callbacks are not set by the omap3 platform init code while being
required by the driver, leading to the fact that they are set by the
driver during it's probe function
typical example are card detect / read only detect callbacks
un-bundling by searching for driver name \"omap_hsmmc in the
arch/arm folder. omap_hsmmc_platform_data is not initialized directly,
but from omap2_hsmmc_info, which is defined in a separate header file
not touched by this patch
additionally hwmod is used to initialize platform data. use
omap_mmc_dev_attr as a key which hwmod uses omap_hsmmc driver.
since all possible values assigned to omap_mmc_dev_attr.flags
are hsmmc specific:
#define OMAP_HSMMC_SUPPORTS_DUAL_VOLT BIT(0)
#define OMAP_HSMMC_BROKEN_MULTIBLOCK_READ BIT(1)
#define OMAP_HSMMC_SWAKEUP_MISSING BIT(2)
