u-boot: disable USB support on qemuarm64 and genericarm64

Browse Source 
qemu USB devices under KVM currently cause reset loop
in u-boot. If u-boot USB support is disabled then
u-boot just ignores the qemu USB devices which
then work with Linux kernel as before.

Issue has been reported to u-boot upstream in:

https://lists.denx.de/pipermail/u-boot/2025-June/591233.html

(From OE-Core rev: ade1069ece5f964edaa7115681d8dbc484ff2c81)
