mmc: sdhci: Make consistent use of CONFIG_MMC_DEBUG for "DEBUG"ging

The "6882a8c sdhci: Add better ADMA error reporting" commit added
sdhci_show_adma_error() which is built when DEBUG is defined.  Since we
already have CONFIG_MMC_DEBUG used elsewhere in this driver, may as well
make consistent use of that config knob instead.
