Add AIKONF4V3 target

[sensei-hacker]

User description

Summary

Adds support for the Aikon F405 V3 flight controller board.

Hardware Specifications

• MCU: STM32F405RGT6
• Gyro: ICM42688P/ICM42605 on SPI1 (CW270 alignment)
• Flash: W25Q128FV 16MB on SPI2
• OSD: MAX7456 on SPI3
• Barometer: BMP280/DPS310 on I2C1
• Motor Outputs: 6 with DMA (full DSHOT support)
• UARTs: 5 (UART1-5)
• LED: PB4, Beeper: PB5
• PINIO: PB7 (10V BEC), PB3 (Camera control)

Key Differences from AIKONF4

• Different gyro: ICM42688P instead of MPU6000
• LED/Beeper pins swapped
• UART5 added (RX-only on PD2)
• All 6 motor outputs have DMA enabled (vs 4 on AIKONF4)
