nwl: Don't turn off clocks and phy on screen blank

Guido Gunther requested to merge guido.gunther/linux-emcraft:imx8-4.18-devkit-dsi-no_clk_reset into imx8-4.18-wip

This makes the display turn on again on unblank like

echo 1 > /sys/class/graphics/fb0/blank ; sleep 1; echo 0 > /sys/class/graphics/fb0/blank

Since we use a different driver in 5.x don't bother using a DT property but let's keep the code so we remember it was there when comparing drivers for mainlineing.

Closes: #32 (closed)
