Add support for IRQ combiners in the Top-level Control and Status Registers (TCSR) hardware block in Qualcomm Technologies chips.
The first patch prevents the ACPI core from attempting to map IRQ resources with a valid ResourceSource as GSIs.
The second patch adds support for ResourceSource/IRQ domain mapping and fixes IRQ probe deferral by allowing platform_device IRQ resources to be re-initialized from the corresponding ACPI IRQ resource.
Both changes described above are conditional on the ACPI_GENERIC_GSI config.
The third patch takes advantage of the new capabilities to implement the driver for the IRQ combiners.
Tested on top of v4.10-rc4.
Changes V10 -> V11: * Add probe table and use it to implement driver presence detection. * Fix kernel doc formatting in drivers/acpi/irq.c and some minor style issues. * Minor bug fixes in the driver.
Changes V9 -> V10: * Add checks for the producer_consumer field to not use produced IRQ resources as consumed. * Minor bug fixes in the driver.
Changes V8 -> V9: * Do not attempt the mapping for non-GSI IRQs during bus scan. * Make some public APIs private to drivers/acpi/irq.c since they are no longer used on other modules.
