This commit adds support for machine.I2S on the mimxrt port. The I2S API is consistent with the existing stm32, esp32, and rp2 implementations. I2S features: - controller transmit and controller receive - 16-bit and 32-bit sample sizes - mono and stereo formats - sampling frequencies from 8kHz to 48kHz - 3 modes of operation: - blocking - non-blocking with callback - uasyncio - configurable internal buffer - optional MCK Tested with the following development boards: - MIMXRT1010_EVK, MIMXRT1015_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK - Teensy 4.0, Teensy 4.1 - Olimex RT1010 - Seeed ARCH MIX Tested with the following I2S hardware peripherals: - UDA1334 - GY-SPH0645LM4H - WM8960 codec on board the MIMXRT boards and separate breakout board - INMP441 - PCM5102 - SGTL5000 on the Teensy audio shield Signed-off-by: Mike Teachman <mike.teachman@gmail.com>
