pci: endpoint: Update drivers for Linux v6.11

Browse Source 
For Linux v6.11, the 'pci_epc_event_ops' structure 'core_init' callback
was renamed to 'epc_init' and a new 'epc_deinit' callback was added.

Update the PCI endpoint drivers for Linux v6.11 by:

 1. Adding tests to conftest to detect the presence of 'epc_init' and
    'epc_deinit'.
 2. Update the drivers as necessary to use the appropriate callback
    depending upon what is present in the kernel.
