Instead of using a GPIO to turn on/off the CAN transceiver, it is better to
use a regulator as some systems may use a PMIC to power the CAN transceiver.

Instead of using a custom binding for retrieving the GPIO that activates the
LCD from devicetree, use a standard regulator.

This approach has the advantage to be more generic.

For example: in the case of a board that has a PMIC supplying the LCD voltage,
the current approach would not work, as it only searches for a GPIO pin.

Since commit 8fe4554f (leds: leds-gpio: adopt pinctrl support) gpio-led driver
has pinctrl support, so setup the gpio led pin via pinctrl and avoid the
following warning:

hog_pins is used to setup the pin functions, and it is not neccesarily used only
for GPIO pins, so use only 'hog' to describe a more generic term.

Add vmmc-supply for mmc device, so that the power to mmc slot can be
turned on by mmc driver if bootloader hasn't done it.

Also remove "okay" status for mmc1/ssp1, as the device has pin conflict
with gpmi-nand.  Actually the device is already disabled since the
mxs-mmc driver adopts pinctrl support because there is no pinctrl setup
for the device in dts.  Make this explicit by removing "okay" status.
