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 PKA drivers and examples were full of include paths missing the
appropriate prefix, or using angle brackets instead of double quotes or
the other way around.

Add generic AES functions that should be able to support all the modes
of operation of the hardware AES crypto engine, i.e. ECB, CBC, CTR,
CBC-MAC, GCM, and CCM.
This makes it possible to easily implement these modes of operation
without duplicating code.

The peripheral core clocks of the PWM timers are gated in PM1+, so these
power modes must be disabled if a PWM timer is running. Use
lpm_register_peripheral() to handle this automatically and dynamically.

The peripheral core clock of the general-purpose timers used by the PWM
driver is the system clock, not the I/O clock.

According to the Procedure Call Standard for the ARM Architecture
(AAPCS) - ABI r2.09 [1], §5.2.1.2, the stack pointer must be
double-word-aligned at a public interface. The stack implementation
being full-descending, this requires that the top of stack be
double-word-aligned too.
