This reverts commit 83f35bc3a852f1c3892c7474998c5cec707c7ba3.
This commit the wrong direction, we should really be changing panel framework to attach dsi host after probe, rather than introducing the same probe-order problem that panels already have to bridges.
The reason is, that in order to deal with devices where display is enabled by bootloader and efifb/simplefb is used until the real driver probes, we need to be careful to not touch the hardware until we have all the pieces probed and ready to go, otherwise you will kill the working display, leaving yourself (at least, in the case of real consumer devices that do not have a debug UART) with no good way to debug what went wrong.
