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
