[PATCH v3 1/9] libcamera: mali-c55: Limit max size to sensor resolution

[Jacopo Mondi]

The Mali C55 ISP cannot upscale. The maximum allowed output size
is the sensor's resolution.

For RAW streams this is already handled in adjustRawSizes(), while
for processed streams the maximum allowed resolution was wrongly
set to the ISP maximum output size (8192x8192).
