The two extcon notifiers are almost the same except for the
variable name for the cable structure and the id notifier inverts
the cable->state logic. Make it the same and replace two
functions with one to save some lines. This also makes it so that
the id cable state is true when the id pin is pulled low, so we
change the name of ->state to ->connected to properly reflect
that we're interested in the cable being connected.

The chipidea/udc.c file sends a CI_HDRC_CONTROLLER_RESET_EVENT to
the wrapper drivers when it calls hw_device_reset(), but that
function is not called from chipidea/host.c. And the udc.c file
sends the CI_HDRC_CONTROLLER_STOPPED_EVENT but the host.c file
doesn't do anything.
The intent of the reset event is to allow the wrapper driver to
do any wrapper specific things after the reset bit has been set
in the usb command register. Therefore, add this event hook in
the host role after we toggle that bit.
Similarly, the intent of the stopped event is to allow the
wrapper driver to do any wrapper specific things after the device
is stopped. So when we stop the host role, send the stopped
event.

We're currently emulating the vbus and id interrupts in the OTGSC
read API, but we also need to make sure that if we're handling
the events with extcon that we don't enable the interrupts for
those events in the hardware. Therefore, properly emulate this

This allows me to get my cable connect/disconnect working

The qcom HSIC ULPI phy doesn't have any bits set in the vendor or
product ID registers. This makes it impossible to make a ULPI
driver match against the ID registers. Add support to discover
the ULPI phys via DT help alleviate this problem. In the DT case,
we'll look for a ULPI bus node underneath the device registering
the ULPI viewport (or the parent of that device to support
chipidea's device layout) and then match up the phy node
underneath that with the ULPI device that's created.
The side benefit of this is that we can use standard properties
in the phy node like clks, regulators, gpios, etc. because we
don't have firmware like ACPI to turn these things on for us. And
we can use the DT phy binding to point our phy consumer to the
phy provider.
The ULPI bus code supports native enumeration by reading the
vendor ID and product ID registers at device creation time, but
we can't be certain that those register reads will succeed if the
phy is not powered up. To avoid any problems with reading the ID
registers before the phy is powered we fallback to DT matching
when the ID reads fail.
If the ULPI spec had some generic power sequencing for these
registers we could put that into the ULPI bus layer and power up
the device before reading the ID registers. Unfortunately this
doesn't exist and the power sequence is usually device specific.
By having the device matched up with DT we can avoid this
problem.

One memory leak fix on the atmel UDC. Several fixes for dwc2. A fix on
composite.c to use usb_ep_free_request() when freeing struct
usb_request.
The opticon driver used a control request at open to trigger a CTS
status notification to be sent over the bulk-in pipe. When the driver
was converted to using the generic read implementation, an inverted test
prevented this request from being sent, something which could lead to
TIOCMGET reporting an incorrect CTS state.
