GCEA/MMHUB EA error should not result to DF freeze, this is
fixed in next generation, but for some reasons the GCEA/MMHUB
EA error will result to DF freeze in previous generation,
diver should avoid to indicate GCEA/MMHUB EA error as hw fatal
error in kernel message by read GCEA/MMHUB err status registers.

Changed from V1:
    make query_ras_error_status function more general
    make read mmhub er status register more friendly

Changed from V2:
    move ras error status query function into do_recovery workqueue

Changed from V3:
    remove useless code from V2, print GCEA error status
    instance number

[Why&How]
Since there is no need for accessing crtc state in the interrupt
handler, interrupts need not be disabled well in advance, and
can be moved to commit_tail where it should be.

requires an indirect IOMMU mapping because the encryption bit
is beyond the DMA mask of the chip.  As such, the two are
