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 adds support for the Mixel DPHY as found on i.MX8 CPUs but since
this is an IP core it will likely be found on others in the future. So
instead of adding this to the nwl host driver make it a generic PHY
driver.

The driver supports the i.MX8MQ. Support for i.MX8QM and i.MX8QXP can be
added once the necessary system controller bits are in via
mixel_dphy_devdata.

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.
