Add S5L8702 VPU-B initialization, reset, bitstream input, frame output, and cache maintenance to the iPod 6G target. Advertise it with HAVE_HW_H264 and append a capability-gated decoder interface to the plugin API. Keep MP4 parsing, AAC decode and mixer output, A/V synchronization, playback controls, resume state, and presentation in the multi-file h264_player plugin. The target layer exposes decoder operations only. Accept non-fragmented MP4/M4V containing Constrained Baseline H.264 through level 3.0, up to 640x480 at 30 fps, with optional AAC-LC audio. Validate codec configuration and all sample-table relationships before activating the hardware. Read MP4 tables in bulk, boost the CPU while preparing them, and report staged loading progress so long movies do not appear to hang during startup. Register the viewer and document its format limits and controls. The libm4a compatibility fixes needed by video-first containers remain in the preceding standalone change. Tested on an iPod Classic 6G through an isolated Rolo nightly runtime: H.264/AAC playback and M4V startup succeeded. Normal and isolated-runtime iPod 6G builds also complete, and git diff --check is clean. Change-Id: I1e96c65c7d0b4231a94f602f8052f1b26d6e4a80

|
* S5L8702 VPU-B IRQ completion for H.264 hardware decoder.
|
|
*
|
|
* VPU-B asserts IRQ 35 (VIC1 bit 3, edge-triggered) on decode completion.
|
|
* These functions provide semaphore-based synchronous wait, replacing
|
|
* the sleep(200ms) polling approach.
