add support vor L4T 35.5.0

[flixr]

start fixing #81

• omitted the patch to apply to disable VB2_BUF_STATE_REQUEUEING as it didn't apply anymore (not sure if that is needed with kernel 5.10, Nvidia seems to have refactored that part of the code)

We use two IMX296 connected to a Orin Nano and since new Orin Nano/NX modules will come with other DRAM we really need L4T 35.5.0 support ASAP.

So far we had no problems with L4T 35.4.1 with streaming and trigger mode (just prints errors if you don't trigger fast enough and run into the timeout).
But with L4T 35.5.0 in trigger mode we get kernel errors after some triggers:

I don't know if that has to do with the dropped patch to disable VB2_BUF_STATE_REQUEUEING which needs to be reworked if that is still needed or something else.
