irqchip/versatile-fpga: Handle chained IRQs properly
[ Upstream commit 486562da598c59e9f835b551d7cf19507de2d681 ]
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.
Fixes: c41b16f8c9d9 ("ARM: integrator/versatile: consolidate FPGA IRQ handling code")
