Adapt the brightness steps as the backlight doesn't light up
for very low duty cycles.

Set #pwm-cells to the default 3 to gain access to the parameter
which allows inverting the PWM signal. This is useful to specify
a backlight which has its highest brightness at 0.
With the change to use the PWM with inverted polarity the PWM signal
is inverted to how it was before this patch.
This changes the meaning of the values in the brightness-levels
property. I.e. the duty-cycle changes from x/255 to (255-x)/255.
Keeping the brightness-levels will then have a big brightness
jump from 0 to 127 duty cycle, the other 6 steps will then be
barely noticeable.
Change the brightness-levels to provide the same brightness-levels
as before.

The Ixora V1.2 carrier board adds SW relevant new features compared to
the V1.1 version.
- An I2C EEPROM is added.
- The SD card slot got a switchable 3.3V supply.
- Pull ups on the SD card signals are not assembled to faciliate 1.8V
speed modes.
- The CAN transceivers got a switchable 3.3V supply.
Add a new device tree and, as the differences are so small rework the
device tree for V1.1 to include the V1.2 device tree and adjust as
needed.
Drop adding the toradex,apalis_imx6q-ixora to the dtb compatible to
adhere to the binding yaml document.

Skov's i.MX6 based boards come in different flavors which have different panels
attached. For optimal contrast experience each panel type needs an individual
common voltage (VCOM) to drive its TFT backplane. The latter is generated by an

regulator to describe this hardware property and parameterize it appropriately
for the different boards.
