[igt-dev] [i-g-t] tests/i915/i915_pm_dc: Remove PC8+ dependency from DC9

[Anusha Srivatsa]

Different from DC6, DC9 does not depend on BIOS/PCU
to execute save and restore or any other sequence when
going to PC9/PC10

DC9 actually depends on D3 and PCODE simply remove power
if SW allowed

v2: resrict the check for igfx only.
