objtool: Allow multiple pv_ops arrays
Having a single large pv_ops array has the main disadvantage of needing all
prototypes of the single array members in one header file. This is adding up
to the need to include lots of otherwise unrelated headers.
In order to allow multiple smaller pv_ops arrays dedicated to one area of the
kernel each, allow multiple arrays in objtool.
For better performance limit the possible names of the arrays to start with
"pv_ops".
