The Netronix board E60K02 can be found some several Ebook-Readers,
at least the Kobo Clara HD and the Tolino Shine 3. The board
is equipped with different SoCs requiring different pinmuxes.

For now the following peripherals are included:
- LED
- Power Key
- Cover (gpio via hall sensor)
- RC5T619 PMIC (the kernel misses support for rtc and charger
  subdevices).
- Backlight via lm3630a
- Wifi sdio chip detection (mmc-powerseq and stuff)

It is based on vendor kernel but heavily reworked due to many
changed bindings.

Currently the parallel panel that is supported is the CLAA WVGA panel,
which is the one that comes with the i.MX51 Babbage board.

The default parallel panel that goes with the imx53-qsb board is
the Seiko 43WVF1G LCD, so switch to the Seiko one.

While at it convert to DRM bindings.

The parallel display still remains disabled as the default display
port is the TVE output.

The cooling device properties "#cooling-cells" should either be present
for all the CPUs of a cluster or none. If these are present only for a
subset of CPUs of a cluster then things will start falling apart as soon
as the CPUs are brought online in a different order. For example, this
will happen because the operating system looks for such properties in the
CPU node it is trying to bring up, so that it can register a cooling
device.

Add such missing properties.
