Used device_for_each_child() to handle child device (dwc3 core) removal
during devexit of dwc3 omap. This is in preparation for creating the child
devices from subnode of dwc3 omap glue using of_platform_populate.

We will be adding support for transceivers on
dwc3 driver but not all boards have controllable
transceivers.

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

Note that once OMAP's transceiver drivers reach mainline,
this glue layer will change accordingly.

if we ever have an omap with multiple instances of

to achieve that, let's use the dwc3_get/put_device_id()

7ae4fc4dc8 usb: dwc3: add a platform device alias
We can have three modules here: dwc3.ko, dwc3-omap.ko and dwc3-pci.ko.
The later have already ids-aliases for probing and is fine. The omap
module has alias for DT but lacks alias for the "native"
platform_device. Maybe we should get rid of it and stick to the DT name?
Both glue modules create a new device for which the dwc3.ko module is
responsible and that one lacks the platform alias.

72246da40f usb: Introduce DesignWare USB3 DRD Driver
The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.

Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.

The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.

More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.

While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.
