drm/i915/dmc: Drop PIPEDMC faults from the fault mask on LNL+
On LNL+ PIPEDMC faults are reported via PIPEDMC interrupts
instead of the direct DE_PIPE_* reporting used on earlier
platforms. Drop the relevant bits from the fault mask.
The bits are tied to zero on LNL, so there is no danger of
spurious fault interrupts even with an incorrect mask.
