Each subfolder can represent a different platform, making it easier to
locate and maintain platform-specific code. Since the code is expected
to grow in the future, let's start organizing it in a folder-based structure
for easier maintenance at a later stage.

Yes, its intention is similar to JH8100. We will submit other clock
domains and PLL at later stage but not so soon.

I am sorry but we started development on FPGA. Unfortunately, the PLL driver
and other domains are planned to be finished at a later stage. I have tried
to minimize the churn as much as possible.
