Subject: gpio/davinci: Prepare gpio_irq_handler for irq argument removal
The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.
Search and update was done with coccinelle and the invaluable help of
Julia Lawall.

Subject: gpio/davinci: Avoid redundant lookup of irq_data
It's pretty silly to do
void *cd = irq_get_chip_data(irq_data->irq);
because that results in cd = irq_data->chip_data, but goes through a
redundant lookup of the irq_data. Use irq_data directly.

Fix a race where a pending interrupt could be received and the handler

Interrupts for GPIOs 16 through 31 are enabled by bit 1 in the
"binten" register (offset 8). Previous versions of GPIO only
used bit 0, which enables GPIO 0-15 interrupts.

Subject: gpio: 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 as most platforms don't use probing.
There appears to be a great deal of blind copy and paste of this code.
