Depending on the use case and on the timings,
aes_auth_crypt_check_status() sometimes never reported an available
result, leading to a deadlock of any protothread waiting for this event,
and to a WDT reset if a protothread was polling it.
This was caused by aes_auth_crypt_start() clearing the result available
interrupt after operations that may rightfully trigger it, leading to a
missed interrupt.

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.

Add functions providing the SoC revision, SRAM size, and enabled
hardware features, as well as a function printing SoC information.

Add functions providing the last reset cause, one as an integer (ID),
and one as a string.

The conditional definitions in project-conf.h depending on
CONTIKI_TARGET_<TARGET_NAME> were ignored at link time, which broke the
linker script if it used these definitions, so the flashed applications
could crash or malfunction.

The block that controls the `.upload` target is unnecessarily replicated in multiple sub-board Makefiles. This was originally done because the SmartRF and the Launchpad can be programmed with the c2538-bsl script, whereas the sensortag cannot.
This commit moves the `cc2538-bsl` / `.upload` target logic to the top level cpu Makefile (`cpu/cc26xx-cc13xx/Makefile.cc26xx-cc13xx`). Board makefiles simply set the make variable `BOARD_SUPPORTS_BSL` to 1 to signal that they can be programmed by the BSL script. If `BOARD_SUPPORTS_BSL` is not equal to 1, trying to use the `.upload` target will return an error message.
For example:
```
$ make BOARD=sensortag/cc2650 cc26xx-demo.upload
using saved target 'srf06-cc26xx'
This board cannot be programmed with the ROM bootloader and therefore does not support the .upload target.
```
