[SRU] [V2] [B/C] [PATCH 0/8] Sync AMD MP2 I2C driver with upstream version

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1787775

v2: Build the driver as module for i386.

[Impact]
AMD MP2 I2C driver doesn't support more than one bus.
This makes touchpad on Lenovo Yoga 530 doensn't work as expected.

[Fix]
Sync the MP2 driver with upstream version.

[Test]
The new upstream driver doesn't break on Latitude 5495.
Users haven't given any feedback yet, but since Disco is freezing I
am sending this out.

[Regression Potential]
Low. It's from upstream, and only a subset of Raven Ridge has this
device.
