usb: dwc3: qcom: Remove extcon functionality from glue layer
Historically Qualcomm DWC3 glue driver supported both extcon and
usb-role-switch kinds of notifications. When Bjorn contributed [1] the
flattened representation for the DWC3 host controller, he also kept both
extcon and usb-role-switch support in the flattened driver & bindings.
Currently there are no in-kernel users for flattened DWC3 and extcon. As
device's DT needs to be manually converted from legacy to the flat DWC3
representation, we can drop (legacy / deprecated) extcon support from
the new DWC3 glue driver, significantly simplifying the code.
This potentially affects flattening effort for the following platforms:
Platforms currently using linux,extcon-usb-gpio device that need to
switch to gpio-usb-b-connector:
- apq8096-db820c,
- msm8996-sony-xperia-tone-dora
Platforms currently using linux,extcon-usb-gpio device that need to
switch to gpio-usb-c-connector (not supported at this moment) or to
implement typec support
- msm8996-sony-xperia-tone-kagura
- msm8996-sony-xperia-tone-keyaki
- msm8998-fxtec-pro1
- msm8998-sony-xperia-yoshino-lilac
- msm8998-sony-xperia-yoshino-maple
- msm8998-sony-xperia-yoshino-poplar
- sda660-inforce-ifc6560

- sdm660-xiaomi-lavender
- sm6125-sony-xperia-seine-pdx201
- sm6125-xiaomi-ginkgo
- sm6125-xiaomi-laurel-sprout
Platforms using TI TUSB320L chip need to switch to represent the USB-C
connector properly (and to have a typec-class driver for the TUSB320L
chip):
- msm8996-xiaomi-gemini
- msm8996pro-xiaomi-natrium
- msm8996pro-xiaomi-scoprpio
