[v2,03/16] mmc: host: omap_hsmmc: cleanup omap_hsmmc_reg_get()

Commit Message

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.
