xtensa: support s6000 gpio irqs and alternate function selection
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
