libsel4platsupport: Add STM32MP2 watchdog support

Add support for controlling the STM32MP2 IWDG watchdog started by TF-A,

seL4 clients can use stm32_iwdg_kick() to refresh or stm32_iwdg_enable(0) to stop it.

stm32_iwdg_init() can be used to return min/max timeout values. stm32_iwdg_set_timeout() can be used to modify the value (default set in TF-A to 32secs).

seL4 Libraries

A collection of libraries for working on seL4.

libsel4allocman: an allocator for managing virtual memory, malloc memory and cspaces.
libsel4bench: a library with utilities for benchmarking on seL4.
libsel4debug: a library with utilities for debugging on seL4. Only useful when debugging a userlevel app; potentially hacky.
libsel4muslcsys: a library to support muslc for the root task.
libsel4platsupport: a wrapper around libplatsupport specificially for seL4.
libsel4simple: an interface which abstracts over the boot environment of a seL4 application.
libsel4simple-default: an implementation of simple for the master branch of the kernel.
libsel4simple-experimental: an implementatoin of simple for the experimental branch of the kernel.
libsel4sync: a synchronisation library that uses notifications to construct basic locks.
libsel4test: a very basic test infrastructure library.
libsel4utils: a library OS - Commonly used stuff, actively maintained: implements threads, processes, elf loading, virtual memory management etc.
libsel4vka: an allocation interface for seL4.
libsel4vspace: a virtual memory management interface for seL4.
