Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * ARMv7 Cortex-A8 and Cortex-A9 Performance Events handling code.
- *
- * ARMv7 support: Jean Pihet <jpihet@mvista.com>
- * 2010 (c) MontaVista Software, LLC.
- *
- * Copied from ARMv6 code, with the low level code inspired
- *  by the ARMv7 Oprofile code.
- *
- * Cortex-A8 has up to 4 configurable performance counters and
- *  a single cycle counter.
- * Cortex-A9 has up to 31 configurable performance counters and
- *  a single cycle counter.
- *
- * All counters can be enabled/disabled and IRQ masked separately. The cycle
- *  counter and all 4 performance counters together can be reset separately.
