The pwm-backlight driver initializes BLON (the enable gpio) to
output-high if the gpio is input on probe. Initializing the gpio
to output-low before the driver probes prevents this action by
the pwm-backlight driver and gets rid of a nasty blink of full
backlight with an uninitialized panel.

Make use of the recently added &pinctrl and &watchdog labels. This
makes the whole file consistent and knowledge of the ahb/apb structure
is hidden.

The cd-gpios signal is assumed active-low by the driver, and the
cd-inverted property is needed if it is, in fact, active-high. Fix
this oversight.

AT91_PINCTRL_OUTPUT_VAL(0) without AT91_PINCTRL_OUTPUT is a no-op, so
make sure the pins really output a zero.

The nattis currently relies on the cmdline to correctly configure the
MTD partition table, and the one given in the device tree is simply
ignored. Which is fortunate, since the device tree partition table is
bonkers and does not match reality.
So, in order to avoid confusion, fix the device tree partition table
to match what is expected (i.e. what is normally provided on the cmdline).
In particular, the rootfs partition should be mtd6.

The used part does contain an eeprom compatible with an Atmel 24c02
chip and it is from NXP, but it is not called 24c02. It's actually a
se97b chip. Adjust the compatible accordingly.
