From: Ming Qian <ming.qian@oss.nxp.com>
Support the upgraded JPEG encoder v1 found on i.MX952 SoC.
V1 hardware uses enhanced descriptors with mode, quality, and
threshold fields, configured in a single phase via setup_desc
callback.
V0 hardware continues using the existing two-phase manual configuration.
