    boards: mimxrt595evk: Setup the regulator for Run mode

    Setup the appropriate voltage in the PMIC based on the
    core frequency.
    Add labels to the regulators for easy access to the nodes.
    Add CONFIG_REGULATOR to the defconfig so we can setup the
    PMIC voltages during platform startup.

To Reproduce Steps to reproduce the behavior:

1. cd tests/kernel/usage/thread_runtime_stats
2. west build -b mimxrt595_evk_cm33
3. west flash
4. See error

Expected behavior clock count for this board is not stable after setting regulator

Impact clock stable issue
