remoteproc: enable halt-on-crash for core dumps
This patch allows you to cause the respecive remoteproc instance to halt when
crashing by writing the string "enable" to the core file:
echo enable > /<debugfs>/remoteproc/<remoteproc>/core.
After this, if the remoteproc crashes, you can extract the core by reading the
same file. You can then resume crash recovery by writing "continue" to the
file. The halt-on-crash will remain enabled, so that subsequent crashes can be
analyzed by pulling the core file again. Writing "disable" will turn off
halt-on-crash so that crash recovery happens immediately. (This means copying
of trace{0,1} to trace{0,1}_last, and resetting the remoteproc.)
