Add system sleep callbacks for the MAX96724 deserializer and the MAX96717 serializer. Use the common serdes suspend helpers to preserve state on suspend, and restore device access and common serdes state on resume before streaming restarts.

Restore minimal hardware state on resume: - Deserializer: restore serializer I2C alias translations and re-run select_links() with RESET_ONESHOT for forwarding pipeline - Serializer: restore cached I2C translations and tunnel mode (if active) - Set resume_reconfigure_pending flag to bypass stale software cache and force full hardware reprogram on next stream start The implementation follows the standard Linux PM model: suspend quiesces hardware, resume reinitializes to clean baseline, and enable_streams() reprograms full runtime configuration when userspace restarts streaming.

On resume, reuse max_des_ser_attach_addr() in re-attach mode instead of the open-coded max_des_resume_restore_serializer_aliases() helper. This consolidates the retry logic and GMSL version pinning in one place and removes the now-redundant helper function. Shorten verbose block comments to single-line comments.

Runs dkms build against multiple kernel families on self-hosted Linux runners: Ubuntu 24.04: 6.12-intel, 6.17-intel, 6.18-intel, 6.17, 7.0 Ubuntu 26.04: 7.0 -intel rows pull headers from the public Intel Linux Overlay (download.01.org) and canonical rows use only Ubuntu archives, with 6.17 / 7.0 arriving via HWE-edge and OEM meta packages. POST_ADD is neutered during 'dkms add'; the upstream source paths extracted for the OOT build are derived from dkms.conf's POST_ADD+= lines so this workflow stays in sync when dkms.conf changes.
