This adds support for the Kontron Electronics i.MX8MP SMARC module
(which uses the OSM-S i.MX8MP SoM) on the Kontron SMARC eval carrier.

Signed-off-by: Frieder Schrempf <frieder.schrempf@kontron.de>
---
Changes for v2:
* Fix GPIO labels
* Add support for TPM chip on SMARC module
* Disable PWM in favor of GPIO5 on SMARC carrier
* Enable LCDIF node to make HDMI work
* Add support for GPIO expanders on SMARC carrier
* Remove SPI flash as its removable and should be in an overlay
* Add CAN regulators to fix transceiver enable

Can we name it regulator-can0?

We would like to end property list with "status".

Can we use a generic node name?

The "okay" status is mostly used to flip "disabled" one.  Not sure we
need it here.
