In preparation to get rid of SDHCI_QUIRK_MISSING_CAPS, replace SDHCI_QUIRK_MISSING_CAPS with __sdhci_read_caps(). __sdhci_read_caps() is also called from sdhci_setup_host() via sdhci_read_caps(), however only the first call to __sdhci_read_caps() does anything because after that host->read_caps has been set to true. Note, __sdhci_read_caps() does more than just set host->caps, such as do a reset, so calling __sdhci_read_caps() earlier could have unforeseen side-effects. However the code flow has been reviewed with that in mind.
