Better subsystem support in Rust

[d3zd3z]

There are various other subsystems that would needed to be analyzed further to understand the work
involved.

• Bluetooth/BLE
• Clock Control
• Comparator
• DMA
• eeprom
• haptics
• led_strip
• pwm
• regulator
• rtc
• stepper
• IPC
• zbus

If possible, please leave the DMA I2C to me. I am currently dedicating myself to learning Rust and hope to assist you in the area of device trees in the near future :)
