mmc: omap_hsmmc: ensure pbias configuration is always done
Go through the driver's set_power() functions rather than calling regulator_enable/disable() directly because otherwise pbias configuration for MMC1 is not done. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Acked-by: Balaji T K <balajitk@ti.com> Signed-off-by: Chris Ball <cjb@laptop.org>
