[RFC v3 0/2] Add support for time DT property in TCPM

USB PD specification defines a bunch of timers that can have a range of
acceptable values instead of specific values. These values have to be
tuned based on the platform. However, TCPM currently sets them to a
default value without providing a mechanism to set platform specific
values.

This patchset adds new DT properties per timer to allow users to define
platform specific values.

Changes compare to v2:
- Added min, max & default values to DT property in Documentation.
- Changed return type of tcpm_fw_get_timings to void instead of int.

Changes compared to v1:
- Defined new properties per timer that we are interested in rather
than defining a single pd-timers u32 array property.
- Better description of the timer properties.
- Since subject has changed, adding link for previous patchset for
posterity:
