Rename driver file to BSEC2.
Split header file in IP and feature parts.
Add functions to access BSEC scratch register.
Several corrections and improvements.
Probe the driver earlier, especially to check debug features.

On closed chips, it is not allowed to open debug. The BSEC debug
register can not be rewritten.
On open chips, the debug is already open, no need to rewrite this
register. This part of code is just removed.
An INFO message is displayed if debug is disabled.
The freeze of the watchdog during debug is also removed.
In case of debug, this must be managed by the software that enables
the debugger.

Introduce driver for STM32 IWDG peripheral (Independent Watchdog).
It is configured according to device tree content and should be enabled
from there.
The watchdog is not started by default. It can be started after an HW
reset if the dedicated OTP is fused.
The watchdog also needs to be frozen if a debugger is attached.
This is done by configuring the correct bits in DBGMCU.
This configuration is allowed by checking BSEC properties.
An increase of BL2 size is also required when adding this new code.
