[SRU][A/B/OEM-X][PATCH 0/2] Fix two front mics problem for more Lenovo m7/8/9xx machines

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1781316

Hope it can catch the last SRU of artful kernel and OEM-X kernel, since the oem
project needs them to be merged to OEM-X.

[Impact]
Recently lenovo project received a couple of lenovo machines, they all have
two mics on front panel, so all these machines need to apply a fixup, otherwise
one of the mics can't work.

[Fix]
apply a fixup from upstream driver, all these mics can work normally.

[Test Case]
plug mics or headset in front mic jacks, the mic/headset-mic can be detected
and can record sound normally.

[Regression Potential]
Very low, the changes are specific to lenovo m7/8/9xx machines with the same
subsystem id or the same init pin cfg table.
