Fix all the remaining dtc 'unit_address_format' warnings except for the ones
related to 'register-bit-led'. For those, we need to decide on and document
the node name.

The GPIO is used to place the BMC-connected TPM in reset. This state is
latched until the BMC is next reset, blocking access to the TPM for that
boot.
On both machines this net is called TPM_RESET_LATCH_B.

The values were determined experimentally via boot tests, not by
measuring the bus behaviour with a scope. We plan to do scope
measurements to confirm or refine the values and will update the
devicetree if necessary once these have been obtained.
However, with the patch we can write and read data without issue, where
as booting the system without the patch failed at the point of mounting
the rootfs.

Set watchdog 1 to pulse the fan watchdog circuit that drives the FAULT
pin of the MAX31785, resulting in fans running at full speed, if at
any point the BMC stops pulsing it, such as a BMC reboot at runtime.
