[patch 2/3] fastboot: turn the USB hostcontroller initcalls into async initcalls

[Arjan van de Ven <arjan@infradead.org>]

From: Arjan van de Ven <arjan@linux.intel.com>
Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls

the USB host controller init calls take a long time, mostly due to a
"minimally 100 msec" delay *per port* during initialization.
These are prime candidates for going in parallel to everything else.

The USB device ordering is not affected by this due to the
serialized-within-eachother property of async initcalls.
