DaVinci SoC updates for v5.1 (part 3)
-------------------------------------
This pull request gets rid of mach-davinci private interrupt controller
implmentations (aintc and cp_initc) and moves them to drivers/irqchip.

mach/irqs.h usage outside of mach-davinci has been rid of.

The driver changes (input and irqchip) have been acked by respective
maintainers.

* tag 'davinci-for-v5.1/soc-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: (57 commits)
  ARM: davinci: remove intc related fields from davinci_soc_info
  irqchip: davinci-cp-intc: move the driver to drivers/irqchip
  ARM: davinci: cp-intc: remove redundant comments
  ARM: davinci: cp-intc: drop GPL license boilerplate
  ARM: davinci: cp-intc: use readl/writel_relaxed()
  ARM: davinci: cp-intc: unify error handling
  ARM: davinci: cp-intc: improve coding style
  ARM: davinci: cp-intc: request the memory region before remapping it
  ARM: davinci: cp-intc: use the new-style config structure
  ARM: davinci: cp-intc: convert all hex numbers to lowercase
  ARM: davinci: cp-intc: use a common prefix for all symbols
  ARM: davinci: cp-intc: add the new config structures for da8xx SoCs
  irqchip: davinci-cp-intc: add a new config structure
  ARM: davinci: cp-intc: add a wrapper around cp_intc_init()
  ARM: davinci: cp-intc: remove cp_intc.h
  irqchip: davinci-aintc: move the driver to drivers/irqchip
  ARM: davinci: aintc: remove unnecessary includes
  ARM: davinci: aintc: remove the timer-specific irq_set_handler()
  ARM: davinci: aintc: request memory region before remapping it
  ARM: davinci: aintc: unify error handling
