In the Liquid8994 we don't need the USB HUB reset and Ethernet reset
from software.

The LiQUID dock driver might probe and attempt to add/remove
the USB host controller device before it has even probed.
Though not fatal, this could lead to the hub ports not being
functional when booting up initially docked. Instead, make
sure USB host controller is ready first by deferring probe
until its driver is present.

The MSM8994 LiQUID docking station does not have a
pin for a dock_enable GPIO, as the USB and Ethernet
ports are always powered via the DC source. Make
this GPIO optional.
As the power to the hub and Ethernet ports may now
be always-on, also make sure to assert the reset lines
prior to adding the USB host controller. This way the
deassertion of the resets will happen after the USB
stack is fully initialized to kick off enumeration.

Check nb parameter of register_liquid_dock_notify() in
order to avoid a potential NULL pointer reference if passed
to blocking_notifier_chain_register().

The LiQUID dock support driver is not specific to the
APQ8084 SoC. Rename it to reflect its generality since
it can be used for other MSM/APQ LiQUID platforms.
