The 7 lines driven by the TCA6507 can either drive LEDs or act as output-only
GPIOs.

To make this distinction in devicetree we use the "compatible" property.

If the device attached to a line is "compatible" with "gpio", we treat it
like a GPIO.  If it is "compatible" with "led" (or if no "compatible" value
is set) we treat it like an LED.

The head number of a given display controller is fixed in hardware and
required to program outputs appropriately. Relying on the driver probe
order to determine this number will not work, since that could yield a
situation where the second head was probed first and would be assigned
head number 0 instead of 1.

By explicitly specifying the head number in the device tree, it is no
longer necessary to rely on these assumptions. As a fallback, if the
property isn't available, derive the head number from the display
controller node's position in the device tree. That's somewhat more
reliable than the previous default but not a proper solution.
