Hi Linus,

here's the latest series of patches that implement the tighter IRQ chip
integration. I've dropped the banked infrastructure for now as per the
discussion with Grygorii.

The first couple of patches are mostly preparatory work in order to
consolidate all IRQ chip related fields in a new structure and create
the base functionality for adding IRQ chips.

After that, I've added the Tegra186 GPIO support patch that makes use of
the new tight integration.

Thanks a lot.

Changes in v7:
- squashes in a few fixes pointed out by Grygorii
- adds a couple of patches on top to support driver conversion

Changes in v6:
- rebased on latest linux-gpio devel branch
- one patch dropped due to rebase

Changes in v5:
- dropped the banked infrastructure patches for now (Grygorii)
- allocate interrupts on demand, rather than upfront (Grygorii)
- split up the first patch further as requested by Grygorii

Not sure what happened in between here. Notes in commit logs indicate
that this is actually version 5, but I can't find the cover letter for
v3 and v4.

Changes in v2:
- rename pins to lines for consistent terminology
- rename gpio_irq_chip_banked_handler() to
gpio_irq_chip_banked_chained_handler()
