NOTE: resending due to missing irqchip maintainers in Cc

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 (9-19) makes the aintc driver suitable for drivers/irqchip
and eventually moves it over there.

Part 3 (20-32) does the same for the cp-intc driver.

Last patch removes unnecessary code.

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

v1 -> v2:
- made commit messages readable without reading the subject line first
- collected David's Reviewed-by tags for patches that haven been
  significantly modified since v1
- added handling of spurious interrupts in cp-intc
- added comments explaining the irq handlers (C versions translated from
  assembly)
- dropped the patches removing the hardware interrupt numbers from
  the priority tables
- don't remove irqs.h, make it a local header instead
- rearranged the patches in order not to remove the code added
  by earlier ones
- renamed d*_init_irqs to d*_init_irq to fit the name of the relevant
  callback in machine info struct
- fixed license identifiers where needed
- added comments to config structures for irqchip drivers
- fixed all off-by-one errors in resource sizes
- clarified the comments on the weird handling of IRQ_TINT1_TINT34 as level
  irq and added missing calls to irq_set_handler() to dm3* SoCs
- fixed one function that was missing a correct prefix in cp_intc
- return value variables should be called ret not rv
- added a patch converting calls to _raw_readl/writel() to their _relaxed
  counterparts
- fixed the commit message prefix in patches that belong to the irqchip
  subsystem
- other minor tweaks
