dt-bindings: clock: qcom,camcc-sm8250: extend clocks and power domains

Add clocks and properties (power-domains, required-opps) already used in
SM8250 DTS:

  sm8250-hdk.dtb: clock-controller@ad00000: clocks: [[46, 10], [44, 0], [44, 1], [45]] is too long
  sm8250-hdk.dtb: clock-controller@ad00000: clock-names:0: 'bi_tcxo' was expected
  sm8250-hdk.dtb: clock-controller@ad00000: 'power-domains', 'required-opps' do not match any of the regexes: 'pinctrl-[0-9]+'
