media: imx-jpeg: Add encoder ops layer for hardware abstraction

Browse source

Introduce mxc_jpeg_enc_ops function pointer structure to abstract
encoder configuration differences between hardware versions.

Extract the existing two-phase manual configuration into dedicated
functions (enter_config_mode/exit_config_mode) for v0 hardware.
Add setup_desc callback placeholder for future v1 hardware support
which will use descriptor-based configuration.

Store the extended sequential mode flag in the context to avoid
recalculating it during configuration phases.

No functional change.
