PL2303HXN is not supported by 5.4 kernel.
5.5 kernel starts to support it. so only SRU for focal 5.4 kernel.

[Fix]
Clean cherry-pick upstream commits.
Add support for PL2303HXN.

[Test]
Verified on hardware, use minicom to test serial port, it works fine.

[Where problems could occur]
It may break the pl2303 ttyUSBx.

This bug is awaiting verification that the linux-iot/5.4.0-1000.2 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
