platform: cznic: turris-omnia-mcu: Add support for MCU connected GPIOs
Add support for GPIOs connected to the MCU on the Turris Omnia board.
This includes:
- front button pin
- enable pins for USB regulators
- MiniPCIe / mSATA card presence pins in MiniPCIe port 0
- LED output pins from WAN ethernet PHY, LAN switch and MiniPCIe ports
- on board revisions 32+ also various peripheral resets and another
voltage regulator enable pin
