Benoît Thébaudeau 8a273a248e cc2538: Add configuration for firmware location
Introduce FLASH_CONF_FW_ADDR and FLASH_CONF_FW_SIZE in order to make it
possible to place the firmware anywhere, regardless of Coffee, and
without having to write a custom linker script. Also, handle the default
values properly in order to fix the link breakage reported by
Arthur Fabre <arthur@arthurfabre.com> with COFFEE_CONF_CUSTOM_PORT.
