Add EDL sysfs entry for mhi controller that provides edl_trigger callback. Add mhi_pci_generic_edl_trigger for qualcomm sdx55,sdx65 and sdx75 as edl_trigger callback. v1->v2: 1. Move all process needed by qualcomm sdx55,sdx65,sdx75 to enter EDL into mhi_pci_generic_edl_trigger() as the callback to edl_trigger. 2. MHI stack creates EDL sysfs entry to invoke edl_trigger callback so that devices need different mechanism to enter EDL can provide its own edl_trigger callabck .
