This is initial mvp implementation for the Pi5 BSP. The
initial support has the following features:
- PL011 debug uart (full termios console driver)
- Arm Generic Timer (virtual interface)
- GIC-V2 interrupts
This will be extended in follow-up work.

Resolving warnings on 3rd-party code can be invasive and will make it
harder to bring in updates from upstream. For issues outside -Wall,
disable the warning for this piece of code instead.
On 32bit systems, int and long are the same size. This is not the case
on 64bit systems. This corrects the maximum value of the stringto type
on those systems.
The function cast from more parameters to fewer parameters is generally
unsafe as the additional parameters will be undefined values that happen
to be in the right registers if it is ever called. Instead of casting
the function pointer, provide a dummy function pointer when the original
function pointer is non-NULL since it is only ever used for a
NULL-check.
libc's strto* functions' behaviour isn't defined when the passed string
is NULL. In glibc it causes a seg fault when I tested it. This could
cause inconsistency.
rtem's stringto* functions didnt previously checked for null before
passing to underlying strto* functions.
Added the check which returns `RTEMS_INVALID_ADDRESS` on failure.
Also added a test case for the same

This warning occurs when comparing a signed variable to an unsigned one.
This addresses warnings that only occurred on 64-bit targets. For the
ones which only appeared on 64-bit targets, the cause was frequently
a mismatch when comparing a combination off_t, ssize_t, and int.
