vgsp: m66 - host-readable TSG fault buffers + post-mortem dump
m65 proved the scheduled QMD never writes its release anywhere (module sem
stays 0, guest page stays 5) - the engine dies or is cancelled before
completion. The TSG fault-method buffers (0xa06c010a) are the hardware's
record of why; force them to host sysmem (the captured aperture, param
gsp_phys_rmcall_faultbuf_sys=1) and dump both buffers' first 8 words in the
post-mortem so an engine fault entry (faulting address/engine) is visible.
