media: ti: j721e-csi2rx: add multistream support

Each CSI2 stream can be multiplexed into 32 independent streams, each
identified by its virtual channel number and data type. The incoming
data from these streams can be filtered on the basis of either the
virtual channel or the data type.

To capture this multiplexed stream, the application needs to tell
the driver how it wants to route the data. It needs to specify
which context should process which stream. This is done via the
new routing APIs.

Add ioctls to accept routing information from the application and save
that in the driver. This can be used when starting streaming on a
context to determine which route and consequently which virtual channel
it should process.

De-assert the pixel interface reset on first start_streaming() and assert
it on the last stop_streaming().
