drivers: Remove CONFIG_OPROFILE support 



The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.

Remove kernel's old oprofile support.

it is possible to use RCU to provide dynamic non-maskable interrupt

how to do this, drawing loosely from Zwane Mwaikambo's NMI-timer

work in "arch/x86/oprofile/nmi_timer_int.c" and in
