-Enclose the chained handler with chained_irq_{enter,exit}(), so that the
-muxed interrupts get properly acked.
-
-This patch also fixes a reboot bug on OX820 SoC, where the jiffies timer
-interrupt is never acked. The kernel waits a clock tick forever in
-calibrate_delay_converge(), which leads to a boot hang.

-Clear its own IRQs before the parent IRQ get enabled, so that the
-remaining IRQs do not accidentally interrupt the parent IRQ controller.
-
-This patch also fixes a reboot bug on OX820 SoC, where the remaining
-rps-timer IRQ raises a GIC interrupt that is left pending. After that,
-the rps-timer IRQ is cleared during driver initialization, and there's
-no IRQ left in rps-irq when local_irq_enable() is called, which evokes
-an error message "unexpected IRQ trap".
