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.

Mixer has ten inputs and five outputs. Accordingly ACIF (Audio
|
|
Client Interfaces) port nodes are defined to represent Mixer
|
|
inputs (port 0 to 9) and outputs (port 10 to 14). These are
|
|
connected to corresponding ports on AHUB (Audio Hub).
