stm32/boards/LEGO_HUB_NO6: Add board definition for LEGO_HUB_NO6. Add basic support for LEGO HUB NO.6 (e.g. LEGO SPIKE Prime, LEGO MINDSTORMS Robot Inventor). See README.md for details. Thanks to @dpgeorge for helping put this together. Signed-off-by: Tobias Thyrrestrup <tt@LEGO.com>

/*
Linker script fragment for mboot on an STM32xxx MCU.
This defines the memory sections for the bootloader to use.
*/
MEMORY

FLASH_BL (rx) : ORIGIN = 0x08008000, LENGTH = 32K
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 120K
}
stm32/mboot: Make all mboot sectors erase/write protected. Prior to this commit, only sector 0 was erase/write protected, which may not be enough to protect all of mboot (especially if mboot lives at a higher address than the start of flash). This commit makes sure all internal flash sectors that mboot lives in are protected from erasing and writing. The linker script must define _mboot_writable_flash_start for this to work.
