Subject: [PATCH v6 15/18] dt-bindings: clock: Add L2 clocks to qcom,krait-cc Documentation

Krait-cc qcom driver provide also L2 clocks and require the acpu_l2_aux
and the hfpll_l2 clock to be provided. Add these missing clocks to the
Documentation. The driver keep support for both old (it did already used
these clocks and we keep the same naming scheme) and this new
implementation and should prevent any regression by this fixup.
