These definitions (-1) were correct when used as a hardware IRQ number,
but are incorrect as a mapped IRQ number.

Make sure that the 'static' keywork is at the beginning of declaration
for arch/xtensa/variants/s6000/include/variant/dmac.h
This gets rid of warnings like
warning: ‘static’ is not at beginning of declaration
when building with -Wold-style-declaration (and/or -Wextra which also
enables it).

Implement an irq chip to handle interrupts via gpio. The GPIO chip
initialization function now takes a bitmask denoting pins that should
be configured for their alternate function.
changes compared to v1:
- fixed bug on edge interrupt configuration
- accommodated to function name change
- moved definition of VARIANT_NR_IRQS to this patch
- renamed __XTENSA_S6000_IRQ_H to _XTENSA_S6000_IRQ_H as requested

There are four slightly different dma engines on the s6000 family.
One for memory-memory transfers, the other three for memory-device.
This patch implements a platform-specific kernel-API to control these
engines. It is needed for the network, video, audio peripherals on
s6000.

Platform initialization sets up the LED heartbeat that is controlled
via GPIO. Requesting the GPIO pins fails, however, as the chip is
only initialized later by a device_initcall().
Fix this up by exporting the initialization function. Let the
platform set up the chip before it starts using it.
