pipeline: rpi: Add new stream flags for PiSP

Browse source 
Add the following new stream flags:

Needs16bitEndianSwap - Indicates that a 16-bit endian swap needs to be
performed on the framebuffer in software.

Needs14bitUnpack - Indicates that a CSI-2 14-bit unpacking (to 16-bits)
needs to be performed on the framebuffer in software.

These are to workaround hardware restrictions in the CFE hardware that
will be supported in a future commit.
