The SoC is the same as ma35d1. I will modify ma35 to ma35d1.

Originally, I intended to create a series of shared drivers.

Okay, I will remove the description.

Okay, I will remove the clock-names.

Because this driver has some status bits located in the sys, it is 
necessary to reference the sys link.

Okay, I will correct this issue.

This is not used and will be removed. Thanks for the reminder.
