arm64: dts: mnt-reform2: add internal display support

This adds support for the internal display of the Reform2 Laptop, which
is connected to the i.MX8MQ via a MIPI-DSI->eDP bridge chip. Clocking
is derived from a system PLL, which provides quite good rate matching
for the single supported display mode and keeps the video PLL free for
usage with the external display, which isn't supported yet.

arm64: dts: freescale: add 'chassis-type' property

A new 'chassis-type' root node property has recently been approved for
the device-tree specification, in order to provide a simple way for
userspace to detect the device form factor and adjust their behavior
accordingly.

This patch fills in this property for end-user devices (such as laptops,
smartphones and tablets) based on NXP ARM64 processors.

arm64: dts: imx8mq-reform2: add sound support

This adds sound support to the Reform2.

It differs from the downstream implementation in that the codec
is used as the BCLK and FSYNC master and the i.MX8MQ only supplies
a fixed 25MHz MCLK from the oscillator. This allows to support
a wider range of audio rates by using the codec PLL and to shut
down the audio PLLs on the i.MX8MQ SoC side.

This adds a basic devicetree for the MNT Reform2 DIY laptop. Not all
of the board periperals are enabled yet, as some of them still require
kernel patches to work properly. The nodes for those peripherals will
be added as soon as the required patches are upstream.

The following has been tested to work:
- UART console
- SD card
- eMMC
- Gigabit Ethernet
- USB (internal Keyboard, Mouse, external ports)
- M.2 PCIe port
