[ARM] integrator: convert to clkdev and lookup clocks by device name
People often point to the Integrator/Versatile/Realview implementations to justify using the consumer name as the sole selector for clocks. Eliminate this excuse by changing the Integrator implementation, so it provides a better example of how it should be done. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
