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.

Notes:
Changes since v2:
- fix pcie reset gpio polarity
- add Fabio's Reviewed-By
Changes since v1:
- remove regulator pseudo-bus
- remove partition layout from spi flash node
- remove unneeded label of the spi flash node
- convert downstream power-on-gpio property of pcie node to a proper
regulator
- sort usb* related nodes alphabetically
- make use of GPIO_ACTIVE_{LOW,HIGH} defines
- replace 0x80000000 iomuxc configs by proper defaults obtained from
u-boot
