[PATCH 0/1][SRU][B][F] Add support for Ambiq micro AM1805 RTC

[AceLan Kao]

BugLink: https://bugs.launchpad.net/bugs/1876667

[Impact]
To enable Ambiq micro AM1805 RTC chip

[Fix]
The patch is provided by Eurotech.
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.
