[SeaBIOS] SeaBIOS recognising USB 3.0 on boot works - partly

Booting with 1 x Phillips USB and 1 x Ventura Ultra attached to the Pixel 2015

I've attached the cbmem -c from Pixel Samus, after a cold boot into
Arch Linux and also following a reboot immediately after.

After a reboot, following a boot, the Philips USB now only appears
just the once, and not twice as on a cold boot.

I've attached a third cbmem -c, from John Lewis 11.11.15 SeaBIOS
RW_LEGACY for the Pixel Samus.

* SAMUS - cold boot

$ cbmem -c


* SAMUS -  reboot

$ cbmem -c


* J.LEWIS 11.11.15 cold boot

- same behaviour with JLEWIS on a cold boot and a reboot - no different

$ cbmem -c
