[PATCH v2] ARM: dts: aspeed: bletchley: remove WDTRST1 assertion from wdt1

[Cosmo Chou]

Remove the external signal configuration from wdt1 to prevent the
WDTRST1 pin from being asserted during watchdog resets.

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.
