Eurotech doesn't want to upstream this driver, because there are some functions are used by Eurotech's platforms only. [Test] Verified on Eurotech's machine and it works well. [Regression Potential] Low, it's a standalone file/driver, so no regression could be introduced. [Misc] We only need this driver in Bionic kernel, but for future possible projects, SRU this to Focal kernel, too.
