soc: nxp: imx943: configure GPT as system timer for power management
Configure GPT timers as system tick source when PM is enabled to resolve
low power mode issues:
- Cortex-M SysTick loses state during mix power-off
- SysTick cannot maintain time during system suspend
Configuration changes:
- Disable Cortex-M SysTick when GPT timer is enabled
- Set GPT clock frequency to 32768 Hz for low power operation, 32k is
reserved in soc level system sleep mode
- Configure system tick rate to 1024 Hz
