configs: arm64: Remove CONFIG_USB_DWCOTG

pelwell · pelwell · commit 51dac8721df5 · 2025-06-05T13:23:53.000+01:00
The downstream dwc-otg driver does not work in 64-bit mode; dwc2 should
be used instead. It follows that there is no point enabling the driver
in arm64 builds, and especially not as a built-in.

Remove CONFIG_USB_DWCOTG=y from the arm64 defconfigs, and save a useful
200kB (~1%) from the uncompressed kernel.
