This uses

 - our nwl mipi dsi controller driver
 - our mixel dphy driver
 - a forward port from NXPs dcss driver from our 4.18 tree
   (which we got from their 4.9/4.14 trees)
 - a forward port NXPs patches to the imx-display-subsystem driver
   from our 4.18 tree (which we got from their 4.9/4.14 trees)

ctxld fails during boot due to its irqsteer dependency. Make us undo
less stuff so that probing again works later on (instead of hanging the
boot).

TODO: check if this works on 4.18 too

0x14000 and 0x14018 are SRC_ADDR and DEST_ADDR in the BLT engine.
0x15C00 are the TX_DESCRIPTOR addresses on Halti5 at least.

This avoids the etnaviv_warn_if_non_sensitive warnings.

The mainline ATF doesn't currently support the FSL_SIP_GET_SOC_INFO call
nor does it have the code to identify different imx8mq SOC revisions so
mimic what NXPs ATF does here.

As a fallback use ATF so we can identify new revisions once it gains
support or when using NXPs ATF.

This adds initial support for the NWL MIPI DSI Host controller found on
i.MX8 SoCs.

It adds support for the i.MX8MQ but the same IP can be found on
i.MX8QXP.

It has been tested on the Librem 5 devkit using DCSS.

SAI module on imx7ulp/imx8m features 2 new registers (VERID and PARAM)
at the beginning of register address space.

On imx7ulp FIFOs can held up to 16 x 32 bit samples.
On imx8mq FIFOs can held up to 128 x 32 bit samples.

New IP version introduces Version ID and Parameter registers
and optionally added Timestamp feature.

VERID and PARAM registers are placed at the top of registers
address space and some registers are shifted according to
the following table:

Tx/Rx data registers and Tx/Rx FIFO registers keep their
addresses, all other registers are shifted by 8.

SAI Memory map is described in chapter 13.10.4.1.1 I2S Memory map
of the Reference Manual [1].

In order to make as less changes as possible we attach an offset
to each register offset to each changed register definition. The
offset is read from each board private data.
