Pull interrupt chip driver updates from Thomas Gleixner:

 - Update the realtek-rtl driver to support multiple interrupt domains
   and remove hardcoded assumptions about the underlying demultiplex
   interrupt

 - Remove the unused IMGPDC driver, which got orphaned when the metag
   architecture was removed long ago.

 - Update the Qualcom PDC interrupt chip driver to support differnent
   versions of the IP block, to properly differentiable between direct
   and GPIO based interrupts and to utilize pass through mode to the
   underlying GIC interrupt.

 - Remove redundant dev_err() and dev_err_probe() invocations in various
   drivers as that error logging has been moved to devm_request_*_irq().

 - Support dynamic MSI-X allocations in the GIC-V3-ITS MSI parent domain
   driver. That's important for VFIO pass through devices to avoid
   reinitialization of the MSI-X space when extending the vector range.
   Such a reinitialization can result is lost interrupts and stale
   devices.

 - Fix a bunch of resource leaks in various driver error paths

 - The usual small improvements all over the place
