media: imx-jpeg: Add support for encoder v1 descriptor configuration

Support the upgraded JPEG encoder v1 found on i.MX952 SoC.

Detect the encoder hardware version via the version register.

The v1 encoder uses an expanded descriptor format that allows all
encoding parameters, including JPEG quality, to be configured directly
in the descriptor.

This removes the manual register-based configuration step required by v0
and reduces the interrupt count from two to one per frame.

V0 encoding flow:
  1. Write quality to registers -> trigger config interrupt
  2. Start encoding -> trigger completion interrupt

V1 encoding flow:
  1. Configure descriptor with all parameters including quality
  2. Start encoding -> trigger completion interrupt
