sysctl arm: Remove binary sysctl support 

Now that sys_sysctl is a generic wrapper around /proc/sys  .ctl_name
and .strategy members of sysctl tables are dead code.  Remove them.

Remove a smattering of ctl_names used in sysctl paths,
and kill the ctl_names in the recently added mach-bcmring.

mach-bcmring never should have had sysctl entries with
.ctl_name set.  The binary sysctl interface has been frozen
for a long time before that code was merged, to prevent
probmes with conflicts and lack of testing.   The sysctl_check
code would have caught this if anyone had ever tested it that way.
So I have simply dropped the binary sysctl support instead of
adding another compat entry into sysctl_binary.c.  Going through
/proc/sys/reboot/warm will still work.
