[PATCH v2 0/3] dt-bindings: connector: usb: provide bindings for altmodes

[Dmitry Baryshkov]

In some cases we need a way to specify USB-C AltModes that can be
supportd on the particular USB-C connector. For example, x86 INT33FE
driver does this by populating fwnode properties internally. For the
Qualcomm Robotics RB5 platform (and several similar devices which use
Qualcomm PMIC TCPM) we have to put this information to the DT.

Provide the DT bindings for this kind of information and while we are at
it, change svid property to be 16-bit unsigned integer instead of a
simple u32.

NOTE: usage of u16 is not compatible with the recenty extended
qcom/qrb5165-rb5.dts DT file. I'm looking for the guidance from DT and
USB maintainers whether to retain u32 usage or it's better to switch to
u16.

Changes since v1:
- Added type:object and fixed 'description' string in the altmodes-list
  definition.
