From: Christopher Spinrath <christopher.spinrath@xxxxxxxxxxxxxx>

The CompuLab Utilite Pro is a miniature fanless desktop pc based on
the i.MX6 Quad powered cm-fx6 module. It features two serial ports,
USB OTG, 4x USB, analog audio and S/PDIF, 2x Gb Ethernet, HDMI and
DVI ports, an on-board 32GB SSD, a mmc slot, and on-board wifi/bt.

Add initial support for it including USB, Ethernet (both ports), sata
and HDMI support.

From: Christopher Spinrath <christopher.spinrath@xxxxxxxxxxxxxx>

The cm-fx6 module has an on-board spi-flash chip for its firmware, an
eeprom (containing e.g. the mac address of the on-board Ethernet),
a sata port, a pcie controller, an USB hub, and an USB otg port.
Enable support for them. In addition, enable syscon poweroff support.
