[SRU] [D/E/Unstable] [PATCH 0/3] Sync intel-lpss workaround with upstream version

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1851901

[Impact]
On new Intel SoC, blacklisting intel-lpss or noapic is needed to make
system boot. Touchpad doesn't work as a side effect.

[Fix]
Write-comining doesn't work for intel-lpss, force it to use uncachable
memory region.

[Test]
User confirmed with the patch series the noapic or blacklisting
intel-lpss can be removed. System boot with a working touchpad.

[Regression Potenial]
Low. Tested on several older Intel laptops, still work without any
issue.
