Instead of only servicing the lowest pending interrupt line, make sure
all pending SoC interrupts are serviced before exiting the chained
handler. This adds a small overhead if only one interrupt is pending,
but should prevent rapid re-triggering of the handler.

There is an offset between routing values (1..6) and the connected MIPS
CPU interrupts (2..7), but no distinction was made between these two
values.
This issue was previously hidden during testing, because an interrupt
mapping was used where for each required interrupt another (unused)
routing was configured, with an offset of +1.
Offset the CPU IRQ numbers by -1 to retrieve the correct routing value.

The driver assigned the irqchip and irq handler to the hardware irq,
instead of the virq. This is incorrect, and only worked because these
irq numbers happened to be the same on the devices used for testing the
original driver.

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

This is a standard IRQ driver with only status and mask registers.
The mapping from SoC interrupts (18-31) to MIPS core interrupts is
done via an interrupt-map in device tree.
