callouts: refactor: merge i2c and fsi callouts
Merge gen_i2c_callouts.pl and gen_proc_fsi_callouts.pl to a single
gen_callouts.pl.
The idea as to have a unified output generated for callouts,
irrespective of bus type. The output will be in YAML, as follows:
<sysfs path> : <Inventory path to be called out>
This will simplify usage for the FRU management code, as well as it
should be easier to support other bus types.
