Provide proper configuration for VGEN3, to make sure it's is always powered
which allows that rail to be automatically switched to 1.8 volts
for proper UHS-I operation. By default it's disabled.
With UHS-I enabled:

If someone wants to add settings to the phy it is necessary to actually add the phy. This commit includes micrel,led-mode that is set to the default value, prepared for someone who wants to change this.

On imx6 the SGTL5000 audio codec supply voltage is 3.3V and
not 2.5V as might have been copied over from other modules.
Output is slightly overamplified if the value is not corrected,
which may lead to signal clipping.

Use a pinmux configuration for SD/MMC card detect and SPI chip
select instead of relying on reset/boot settings. There have
been no adverse effects observed, but it seems sensible to mux
the pads explicitly.
