boards: arm: Add wdog support on mimxrt595_evk
Add watchdog support to the mimxrt595 platform.
The mimxrt595 platform is excluded from the watchdog
test case because the test case uses variables in the
noinit section that need to be retained through a reset
but the rt595 does not retain this memory through a
reset.
