mmc: host: omap_hsmmc: use regulator_is_enabled to find pbias status
Use regulator_is_enabled of pbias regulator to find pbias regulator status instead of maintaining a custom bookkeeping pbias_enabled variable. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Tested-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
