[3/7] media: atomisp: Clamp width to max 1920 pixels when in ATOMISP_RUN_MODE_PREVIEW
Commit Message
The pipeline firmware-binaries used in previed mode have
ia_css_binary_xinfo.output.max_width set to 1920.
This causes ia_css_binary_find() to fail when trying to set a higher
resolution resulting in the dump_stack() call in ia_css_binary_find()
triggering and resulting in the try_fmt() or set_fmt() IOCTL failing.
Fix this by clamping the width to max 1920 when in preview mode.
