Add nodes for MIPI DSI and LCDIF on IMX8MM
I'm currently working with a set of patches to convert drm/exynos to a bridge [1] and add IMX8MM support [2] in order to get IMX8MM DSI working for display with a Raspberry Pi DSI touchscreen compatible with a Toshiba TC358762 DSI bridge and Powertip PH800480T013-IDF02 touchscreen.
I had this working on a 5.10 kernel with the old blk-ctl and power-domain drivers that didn't make it into mainline but my 5.15 series with blk-ctl backported from next hangs right after "[drm] Initialized mxsfb-drm 1.0.0 20160824 for 32e00000.lcdif on minor 0" so I assume I have a power-domain not getting enabled.
Please let me know if you see an issue with the way I've configured power-domain or clocks here.
I'm reworking back on top of drm-misc-next, may be I will let you know in couple of days.
