The WDTRST1 pin was originally configured to reset the TPM during watchdog events. However, the pin is incorrectly routed to SRST# on the hardware, causing unintended system resets. Since the TPM is not currently utilized on this platform, remove the external signal configuration to avoid the incorrect reset behavior.
