3d0c31e60e stm32/mboot: Move some BSS vars to new section that isn't zeroed out. 
Zeroing out data on startup takes time and is not necessary for certain
variables.  So provide a declaration for such variables and use it.

Mboot is a custom bootloader for STM32 MCUs.  It can provide a USB DFU
interface on either the FS or HS peripherals, as well as a custom I2C
bootloader interface.
