PR Description

Currently, the ad469x_evb/de10nano tries to use the HPS generated clock as a source of 160MHz clock.
However, this is automatically limited to 100MHz, due to part limitations: #1749 (comment)

https://www.intel.com/content/www/us/en/support/programmable/articles/000084690.html

This PR changes it so the 160MHz clock is generated by a PLL.

defaults to a maximum 100MHz clock.
