powerpc: Fix build failure when CONFIG_USB=y

We are enabling USB unconditionally which results in following build failure

drivers/built-in.o: In function `tb_drom_read':
(.text+0x1b62b70): undefined reference to `usb_speed_string'
make: *** [vmlinux] Error

Enable USB only if USB_SUPPORT is set to avoid such failures
