Subject: [RFC 0/2]  Add support for "pd-timers" 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 a new DT property called "pd-timers" to allow users
to define platform specific values.
