BugLink: https://bugs.launchpad.net/bugs/1882248

This patch is cced to stable, so it will be in the ubuntu kernels
with stable update, but our oem project is waiting for this patch
to be in the oem-b kernel, send it to oem-b first.

[Impact]
On a Dell machine without internal spk and internal mic, after freshly
install the bionic on it, and users plug a headset, the sound couldn't
output from headset.

[Fix]
reverse the order of headset mic and headphone mic

[Test Case]
freshly install the bionic with this patch on that dell machine,
plug headset and play sound, we could hear the sound from headset.

[Regression Risk]
Low, this patch only affects the machine without internal mic and
internal spk, and I already tested this patch on the machine without
internal mic and internal spk, it worked well.
