arm64: tegra: APE sound card for Jetson AGX Orin

Add audio-graph based sound card support on Jetson AGX Orin
platform. The sound card binds following modules:
 * I/O interfaces such as I2S and DMIC (to be specific I2S1,
   I2S2, I2S4, I2S6 and DMIC3 instances).
 * HW accelerators such as MVC, SFC, AMX, ADX and Mixer (all
   the available instances).
