- Introduce `val_pcie_enable_dpc()` and `val_pcie_disable_dpc()` helper functions to manage DPC trigger enable bits in the DPC capability structure. - Use these APIs to disable DPC for all Root Ports and Downstream Ports during PCIe device table creation to avoid unintended error signaling. - Update Exerciser test e024 to call the new API for disabling DPC instead of manually clearing control register bits. - Update relevant headers and extend copyright year to 2026. - Fixes ARM-software#192 Change-Id: I8450efdc15d582bdbbddc90a8c885991613039e5
