d17cab4451 irqchip: Kill off set_irq_flags usage
set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

d2aa914d27 irqchip/vt8500: Use irq_set_handler_locked()
Use irq_set_handler_locked() as it avoids a redundant lookup of the
irq descriptor.

Search and replacement was done with coccinelle:

@@
struct irq_data *d;
expression E1;
@@

-__irq_set_handler_locked(d->irq, E1);
+irq_set_handler_locked(d, E1);

41a83e06e2 irqchip: Prepare for local stub header removal
The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
the local irqchip.h became an empty shell, which solely includes
include/linux/irqchip.h

Include the global header in all irqchip drivers instead of the local
header, so we can remove it.

LTO patches add __visible to the asmlinkage define, causing
compilation warnings like:

vt8500_handle_irq() and vt8500_irq_init() are only referenced in this file, so
make them static.
