i2c: designware-pci: Group AMD NAVI quirk parts together

[ Upstream commit 65769162ae4b7f2d82e54998be446226b05fcd8f ]

The code is ogranized in a way that all related parts
to the certain platform quirk go together. This is not
the case for AMD NAVI. Shuffle code to make it happen.

While at it, drop the frequency definition and use
hard coded value as it's done for other platforms and
add a comment to the PCI ID list.
