dt-bindings: ASoC: Document Tegra264 APE support
Add Tegra264 compatible strings to APE subsystem device bindings:
- audio-graph-card: Due to different PLL clock rate.
- admaif: Due to 32 channels supported and register offset changes.
- i2s: Due to 32 channels supported and register offset changes.
- amx/adx: Due to 32 channels supported and register offset changes.
- asrc: Due to different ARAM address.
- ahub: Due to AHUB IPs number of instances updates.
- for future proofing the T264 compatibility is added for other device
  nodes.

These bindings enable the enhanced audio features of Tegra264
while maintaining compatibility with existing platforms.
