warm-reboot: add cfam-reset capabilities

A cfam-reset is required when doing a warm reboot of a POWER based
processor.

This commit has dependencies on two other commits:

libgpiod dependency in the op-proc-control recipe:
https://gerrit.openbmc-project.xyz/c/openbmc/meta-openpower/+/29076

witherspoon device tree update to name cfam-reset gpio:
https://lists.ozlabs.org/pipermail/openbmc/2020-February/020425.html

Other systems which require this support will also need to have their
dts updated. This will happen as support is needed for warm reboot on
them.

Tested:
Built witherspoon image and verified new procedure runs without failure
within QEMU.
