Andrew Leech 338635ccc6 stm32/main: Add configuration macros for board to set heap start/end. 
The macros are MICROPY_HEAP_START and MICROPY_HEAP_END, and if not defined
by a board then the default values will be used (maximum heap from SRAM as
defined by linker symbols).

As part of this commit the SDRAM initialisation is moved to much earlier in
main() to potentially make it available to other peripherals and avoid
re-initialisation on soft-reboot.  On boards with SDRAM enabled the heap
has been set to use that.
