[PATCH v4 1/4] mmc: core: select HS400 from HS200 tuning function

[Simon Horman <horms+renesas@verge.net.au>]

Call mmc_select_hs400() from mmc_hs200_tuning().

This should have no run-time effect as the existing call to
mmc_select_hs400() is right after a call to mmc_hs200_tuning() in
mmc_init_card() and that is the only caller of mmc_hs200_tuning().

This is in preparation for adding a new mmc_host_opp to be called
after tuning and selecting HS400 - or in other words,
after mmc_execute_tuning() and mmc_select_hs400().
