>> Add sdhci support for MACCHIATOBin boards.  This uses the AP806 SDHCI
>> for eMMC and CP110 master for the SD card slot.

>> This version labels up the uSD connector, adds the vqmmc regulator for
>> the uSD (the regulator itself already present in the DT), and supports
>> the card detect signal.
>>
>> For eMMC, this version adds the vqmmc regulator, which again is already
>> present in the DT, marks it as not supporting SD or SDIO, and also
>> includes "slow mode" since testing with previous versions of the driver
>> have shown that selecting faster speeds results in errors.
