Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SET_SYSTEM_SLEEP_PM_OPS are only used
when the CONFIG_PM_SLEEP is enabled. Unnecessary CONFIG_PM ifdefs
are removed.

Multiple dwc3 probe calls try to allocate no_op_xceive platform
device. Having static IDs for these will throw sysfs error -EEXIST.
Changing these static platform device IDs to AUTO to enable
multiple dwc3 controller support on a SoC.

The devm_ functions allocate memory that is released when a driver
detaches. This makes the code smaller and a bit simpler.

We are removing plat data which was used till now to init and
exit phy. We no longer need this since dwc3-core takes care of
initializing and shutting-down the phy using usb_phy_init()
and usb_phy_shutdown().

The lockless implementation of the unique id is quite impressive (:P)
but dirver's core can handle it, we can remove it and make our code a
little smaller.

We will be adding support for transceivers on

For those which don't provide controllable transceivers
we will register nop transceivers.
