[PATCH 00/35] ARM: davinci: modernize the irq support

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

This series ports the davinci platform to using SPARSE_IRQ, cleans up
the irqchip drivers and moves them over to drivers/irqchip.

The series can be logically split into four parts. The first (1-8) aims
at introducing support for SPARSE_IRQ. It contains a couple changes
required for that functionality and the final patch actually selecting
it.

Second part (9-18) makes the aintc driver suitable for drivers/irqchip
and eventually moves it over there.

Part 3 (19-31) does the same for the cp-intc driver.

Last part (32-35) aims at removing mach/irqs.h as it's no longer needed
with SPARSE_IRQ selected.

The series has been tested on da850-lcdk (for cp-intc) and
dm365-evm (for aintc).
