The csot-pna957qt1-1 is a 10.95" TFT panel. The MIPI controller on this
panel is the same as the other panels here, so add this panel to this
driver. From the datasheet, MIPI needs to keep the LP11 state before
the lcm_reset pin is pulled high, so increase lp11_before_reset flag.

Drop the part about LP11. You must have copied it from an earlier
panel where that flag still made sense. It doesn't make sense to talk
about given the current state of the driver.

nit: can you keep the functions sorted to match the bindings? So this
function would be in between the BOE init function and the IVO init
function?

nit: similarly, sort the default_mode / desc between the BOE one and
the IVO one.
Other than small nits, this looks pretty nice to me and I'd expect to
give a Reviewed-by tag on v2 unless something major changes.
