    sdhci - Add tunables for disabling SDMA and/or ADMA2, and for testing ADMA2.
    
    * Also document hw.sdhci.debug tunable while there.
    
    * Limit ADMA2 support to the already tested and working Intel sdhci
      controllers for now. Currently we only explicitly match against the Intel
      models in sdhci_acpi(4).
      XXX sdhci_pci(4) should explicitly match against the Intel sdhci
          controllers as well to whitelist ADMA2 support, via the
          SDHCI_QUIRK_WHITELIST_ADMA2 flag.
    
    * For testing on not-yet whitelisted models, add the hw.sdhci.adma2_test
      tunable to skip the whitelist check.
