media: cedrus: Rework subsampling handling to allow 4:2:2 destinations
This reworks subsampling handling to allow decoding 4:2:2 (and 4:4:4)
JPEG without downsampling to 4:2:0. The configured destination pixel
format is checked to support the coded subsampling and downsampling is
only applied for 4:2:0 destination pixel formats.
The JPEG subsampling information is obtained from the structure
returned by the common helper instead of a custom switch/case.
Note that the so-called 422T subsampling (also known as 440) is dropped
from the list since the common helper does not support it and will
error out when encoutering it anyway.
