Bug#1134104: linux-image-arm64: enable PHY_NXP_PTN3222 for Lenovo T14s Snapdragon USB support

Dear Maintainer,

While porting Debian to the Lenovo T14s Snapdragon X Elite [1], the
debian/6.19/trixie-backports kernel does not build the PHY_NXP_PTN3222
device driver as a module [2].

This makes the USB ports on the right of the laptop unusable with the
Debian kernels. The x1e87100-lenovo-thinkpad-t14s.dtsi declares multiple
nodes with compatible = "nxp,ptn3222" [3].

The PHY_NXP_PTN3222 config option is built as a module in the upstream
arm64 defconfig [4], so I believe it should also be enabled for the
Debian arm64 kernels in order to provide USB support on the Lenovo T14s
which is mass produced.

I intend to send pull requests to the linux salsa repository and use
this bug as a tracking bug for making sure the fix arrives to
trixie-backports.

Thanks.

Agathe.
