[PATCH v2 6/6] mmc: omap_hsmmc: Don't expect MMC1 to always have vmmc supply

[Rajendra Nayak]

MMC1 is not the only instance that can be used/wired for SD.
So remove this assumption from the driver.

Now that all the mmc id based usage is removed, get rid
of all the DEVID defines and also the 'id' field from the
omap_hsmmc_host structure.
