[SRU][Bionic/OEM-B/Cosmic/Disco][PATCH 0/3] Add support for ALC3277 codec on new Dell edge gateways

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1807334

This patchset is for the Dell Edge IoT Gateway Gen2 project. The pachset
for Gen1 is already merged to b/c/d kernel, and this patchset is partly
based on Gen1's patches. Originally Shrirang is the developer of this driver,
but later he had a new OEM project, then I took over the left work about this
driver.

The machine driver of the Gen2 is accepted by upstream, so it is time to
backport it to b/c/d and oem-b kernel.

there are 3 patches for each kernel:
0001-xxx.patch is to move the gpio from codec driver to machine driver
0002-xxx.patch is to add the machine driver
0003-xxx.patch is to enable the Kconfig for this machine driver

[Impact]
The Dell Edge IoT Gateway is based on kabylake, and the audio codec is alc3277
which is connected to kabylake PCH via SSP0, there is no ASoC machine driver
for this board, so the audio (line-out and line-in) can't work.


[Fix]
write a ASoC machine driver for this board, and this driver is based on
the existing driver kbl_rt5663_max98927.c


[Test Case]
play sound via line-out jack, record sound via line-in jack, all work well.


[Regression Potential]
Very low, this machine driver is specific to Dell Edge IoT Gateway. Only
the machine with the HID:10EC3277 in the BIOS can use this driver.
