samples: rtxxx-amp: Enable mimxrt700_evk/mimxrt798s/hifi4

VitekST · fabiobaltieri · commit 9969ae59d9c0 · 2025-07-31T10:52:33.000+01:00
Add remote target selection. Explicitly enable GPIO support in
amp_blinky. Disable peripherals driven from the hifi4 domain in the
cm33_cpu0 domain to overcome resource conflicts. Select mailboxes for
amp_mbox. Set CONFIG_DMA_TCD_QUEUE_SIZE for amp_audio_output and
amp_audio_loopback. Select i2s devices for amp_audio_loopback.
