cfam-reset: utilize new sysfs interface if avaialble

The kernel introduced support on some systems for a sysfs based
mechanism to issue cfam resets. See the following commit for more
information:
https://github.com/openbmc/linux/commit/0298c9857e284aae7841a31c2a6cd3954afec6c9

Userspace software should first look to utilize the new sysfs based
mechanism and if not available, fall back to the libgpiod mechanism.

Currently only witherspoon-tacoma and rainier support this new sysfs
based cfam reset mechanism.

Tested:
- Built a witherspoon image and verified libgpiod path was used
- Built a witherspoon-tacoma and verified new sysfs path was used
