mmc: sdhci-iproc: Replace SDHCI_QUIRK_MISSING_CAPS
SDHCI_QUIRK_MISSING_CAPS is not needed because __sdhci_read_caps() can be
called instead.
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.
