Migration to busDevice infrastructure

[digitalentity]

Migrate devices to busDevice infractructure:

• ACC/GYRO code (Migration to busDevice infrastructure: acc/gyro/mag/osd #2290)
• Compass (Migration to busDevice infrastructure: acc/gyro/mag/osd #2290)
• MAX7456 OSD (Migration to busDevice infrastructure: acc/gyro/mag/osd #2290)
• OLED display
• PCA9685
• Airspeed sensors (MS4525)
• Rangefinder code (hcsr04_i2c, srf10, vl53l0x)
• RX_SPI
• VTX
• SD Card
• Dataflash

Refactor and cleanup buses implementation:

• Unify SPI & SoftSPI implementation
• Unify I2C & SoftI2C implementation
• Refactor I2C & SPI implementation so we are operating bus ID's and not STM32 peripheral instances
• Add asynchronous/background bus access using DMA
