Add sdhci support for MACCHIATOBin boards. This uses the AP806 SDHCI
for eMMC and CP110 master for the SD card slot.
Signed-off-by: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>

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.
