The fixup ALC256_FIXUP_SKIP_FORCE_RESUME is for fixing the hdmi audio
problem after resuming, and this problem only happens under oem-b
kernel, so this fixup is only needed for oem-b kernel, for D/E and
future kernels, they don't need this patch because fallback_tbl will
apply HEADSET_MIC fixup to these machines automatically.

[Impact]
The external mic can't be detected and can't record sound.

[Fix]
apply an fixup ALC255_FIXUP_DELL1_MIC_NO_PRESENCE


[Test Case]
test the kernel with this patch, the headset mic can be detected and
can record sound.

[Regression Risk]
Low, this quirk is specific to 2 dell machines.
