gemini: Bump to kernel v6.6

The Gemini works fine with kernel v6.6.

As per the example for ipq806x, drop support for anything
older than v6.6, there is no point in supporting it,
and the new DTS SoC directory just makes it hard to
maintain.

-Subject: [PATCH 09/29] fotg210-udc: Support optional external PHY
-
-This adds support for an optional external PHY to the FOTG210
-UDC driver.
-
-Tested with the GPIO VBUS PHY driver on the Gemini SoC.
