Subject: [PATCH] dt-bindings: clock: qcom,videocc: correct clocks per variant

Different SoCs come with a bit different clock inputs:

  sm8250-mtp.dtb: clock-controller@...0000: clock-names:0: 'bi_tcxo' was expected
  sm8250-mtp.dtb: clock-controller@...0000: clock-names: ['iface', 'bi_tcxo', 'bi_tcxo_ao'] is too long
