media: aspeed: Support aspeed mode to reduce compressed data
aspeed supports differential jpeg format which only compress the parts
which are changed. In this way, it reduces both the amount of data to be
transferred by network and those to be decoded on the client side.
2 new ctrls are added:
* Aspeed HQ Mode: to control aspeed's high quality(2-pass) compression mode
This only works with yuv444 subsampling.
* Aspeed HQ Quality: to control the quality of aspeed's HQ mode
only useful if Aspeed HQ mode is enabled
Aspeed JPEG Format requires an additional buffer, called bcd, to store
the information about which macro block in the new frame is different
from the previous one.
To have bcd correctly working, we need to swap the buffers for src0/1 to
make src1 refer to previous frame and src0 to the coming new frame.
