This commit adds preliminary support for ST's new STM32N6xx MCUs. Supported features of this MCU so far are: - basic clock tree initialisation, running at 800MHz - fully working USB - XSPI in memory-mapped mode - machine.Pin - machine.UART - RTC and deepsleep support - SD card - filesystem - ROMFS - WiFi and BLE via cyw43-driver (SDIO backend) Note that the N6 does not have internal flash, and has some tricky boot sequence, so using a custom bootloader (mboot) is almost a necessity.
