add a reference clock for compatibility

Why? This block suddenly has 2 clocks instead of 1?

In fact, there is a reference clock which comes from 26M oscillator
directly. I ignore it because it is a fixed-clock in DTS, and always
turned on for mt8173. But later, I find that I made a mistake before
when I bring up it on a new platform whose reference clock comes from
PLL, and need control it. So here add it, no matter it is a fixed-clock
or not.

Add this explanation to the changelog.
