mmc: host: omap_hsmmc: cleanup omap_hsmmc_reg_get()
No functional change. Instead of using a local regulator variable in omap_hsmmc_reg_get() for holding the return value of devm_regulator_get_optional() and then assigning to omap_hsmmc_host regulator members: vcc, vcc_aux and pbias, directly use the omap_hsmmc_host regulator members.
