drivers/ipmi: add code to set BMC/IPMI enablement from jumper
Some boards, like the Supermicro X11SSM-F, have a jumper for enabling or
disabling the BMC and IPMI. Add a new devicetree driver option to set
the GPIO used for the jumper and enable or disable IPMI according to its
value.
This gets used in a follow-up change by Supermicro X11SSM-F.
Test: Boot with jumper set to each enabled and disabled and check debug
log if IPMI gets enabled/disabled accordingly.
Successfully tested on Supermicro X11SSM-F with CB:48095.
