clocksource: Add a new timer-ingenic driver This driver handles the TCU (Timer Counter Unit) present on the Ingenic JZ47xx SoCs, and provides the kernel with a system timer, a clocksource and a sched_clock.

clocksource/drivers/ingenic: Add high resolution timer support for SMP/SMT. Enable clock event handling on per CPU core basis. Make sure that interrupts raised on the first core execute event handlers on the correct CPU core. This driver is required by Ingenic processors that support SMP/SMT, such as JZ4780 and X2000.

clocksource/drivers/ingenic: Add high resolution timer support for SMP/SMT. Enable clock event handling on per CPU core basis. Make sure that interrupts raised on the first core execute event handlers on the correct CPU core. This driver is required by Ingenic processors that support SMP/SMT, such as JZ4780 and X2000.
