The Intel BMG GPU device supports the crashlog feature, which was
exposed in an Xe driver patch (drm/xe/vsec: Support BMG devices),
however the version of crashlog used by the BMG GPU does not have
a supporing PMT driver.

Update the PMT crashlog driver to support the BMG crashlog feature.

v2:
 - fix a misconfig for the crashlog DVSEC info in the xe driver
 - address review comments
v3:
 - re-order bug fix patches for stable
 - added re-order trigger logic patch
 - added helper patch to address repeated code patterns
 - address review comments
v4:
 - added pcidev to intel_pmt_entry to address null issue
 - dropped endpoint update patches
 - patch cleanup and address review comments
v5:
 - renamed helpers to avoid namespace issues
 - separate mutex cleanup from gaurd usage
 - refactor base paramters to a separate patch (from version struct)
 - add r/b reviewed patches
