mmc: core: Set clock after changing timing immediately for mmc_select_hs400es()

Browse Source 
This's what mmc_select_hs400() or mmc_select_hs() did,
since mmc_set_clock() will let sdhci_arasan_set_clock()
update the PHY clock to match the timing, otherwise
the following mmc_switch_status() will be failed.
