mmc: core: complete HS400 before checking status
We don't have a reproducible error case, yet our BSP team suggested that
the mmc_switch_status() command in mmc_select_hs400() should come after
the callback into the driver completing HS400 setup. It makes sense to
me because we want the status of a fully setup HS400, so it will
increase the reliability of the mmc_switch_status() command.
