[PATCH v9 08/19] hw/arm/npcm7xx: Keep the automatic hub

[Jamin Lin <jamin_lin@aspeedtech.com>]

The OHCI companion has one port, so a second device only fits behind
the hub.

npcm7xx has no versioned machine type, so compat cannot reach it. Turn
the property on here instead. The companion shares the EHCI bus, so
the EHCI carries the property.
