mmc: host: omap_hsmmc: use mmc_regulator_get_supply() to get regulators
In preparation for using the generic mmc binding for io regulator ("vqmmc"), use mmc_regulator_get_supply() to get vmmc and vqmmc regulators. Only if "vqmmc" regulator isn't found, fallback to use "vmmc_aux" regulator. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
