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, but it is more logical since SVID is 16 bits wide. Changes since v3: - Added enum to constraint atmode SVID (Rob) - Moved additionaPropperties to come beore the property definitions (Rob) Changes since v2: - Inlined altmode definitions instead of having them under $defs (Rob) - Explicity list permitted AltMode names (currenty only displayport is allowed) (Rob) Changes since v1: - Added type:object and fixed 'description' string in the altmodes-list definition.
