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

Signed-off-by: Shawn Guo <shawnguo@kernel.org>
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.

There is a significant time required for PHY Micrel KSZ8041 to power up.
Add a delay on start-up/wake-up before the FEC starts communicating with
the PHY.

~11 ms before starting any programming on the MIIM.
Counting that, add a 200 ms delay to be sure the PHY is ready for
programming. Also, add the same off delay time to give the capacitor
time to discharge in order to properly reset.
