Add support for Xilinx QDMA Soft IP core as Root Port.
The Versal Prime devices support QDMA soft IP module in programmable logic.
The integrated QDMA Soft IP block has integrated bridge function that can
act as PCIe Root Port.

Use MSI_FLAG_NO_AFFINITY, which keeps .irq_set_affinity() unset and allows
migrate_one_irq() to exit right away, without warnings like this:
IRQ...: set affinity failed(-22)
Remove the .irq_set_affinity() implementation that is no longer needed.

Currently, if the function irq_domain_add_linear() fails to allocate
a new IRQ domain and returns NULL, we would then still return a success
from the xilinx_pl_dma_pcie_init_irq_domain() function regardless, as
the PTR_ERR(NULL) would return a value of zero. This is not a desirable
outcome.
Thus, fix the incorrect error code and return the -ENOMEM error code if
the irq_domain_add_linear() fails to allocate a new IRQ domain.

The error paths that follow calls to the devm_request_irq() functions
within the xilinx_pl_dma_pcie_setup_irq() reference an uninitialized
symbol each that also so happens to be incorrect.
Thus, fix this omission and reference the correct variable when invoking
a given dev_err() function following an error.
This problem was found using smatch via the 0-DAY CI Kernel Test service:
drivers/pci/controller/pcie-xilinx-dma-pl.c:638 xilinx_pl_dma_pcie_setup_irq() error: uninitialized symbol 'irq'.
drivers/pci/controller/pcie-xilinx-dma-pl.c:645 xilinx_pl_dma_pcie_setup_irq() error: uninitialized symbol 'irq'.

There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.
./drivers/pci/controller/pcie-xilinx-dma-pl.c:688:2-9: line 688 is redundant because platform_get_irq() already prints an error
./drivers/pci/controller/pcie-xilinx-dma-pl.c:702:2-9: line 702 is redundant because platform_get_irq() already prints an error
