[PATCH 04/32 v3] USB: EHCI: remove Loongson 1B EHCI driver.

From: Florian Fainelli
Date: Fri Oct 05 2012 - 12:22:19 EST


The platform code registering the Loongson 1B EHCI driver has now been
converted to register the ehci-platform driver instead, thus obsoleting the
ehci-ls1x driver, which can be removed.
