a1d5f342d5 pcie: endpoint: Add support to build with k6.9 
Few of the APIs from msi are deprecated in the
kernel 6.9. These APIs are:
  platform_msi_domain_alloc_irqs
  platform_msi_domain_free_irqs

The change is with commit commit 1a4671ff7a903e87 ("platform-msi: Remove
unused interfaces")

Add support to not use these APIs via conftest.

971680aadb PCI: Fix endpoint DMA test for Linux v6.9 
Building the PCI EPF DMA test driver for Linux v6.9 is failing because
the parameters for the pci_epf_alloc_space() function has been updated
to pass the alignment value via the 'pci_epc_features' structure instead
of passing the value directly.

Instead of hard-coding the endpoint alignment in the EPF DMA test driver
use the 'pcie_epc_get_features()' function to retrieve the endpoint
features structure which has the endpoint alignment.

By using the conftest script to detect the parameters for the
pci_epf_alloc_space() function, we can then pass the appropriate
arguments to the pci_epf_alloc_space() function.
