pinctrl: qcom: sc7180: Add new qup functions
on sc7180 we have cases where multiple functions from the same qup instance share the same pin. This is true for qup02/04/11 and qup13. Add new function names to distinguish which qup function to use. The device tree files for this platform haven't landed in mainline yet, so there aren't any users upstream who should break with this change in function names, however, anyone using the devicetree files that were posted on the lists and using these specific function names will need to update their changes.
