dt-bindings: clock: Add "qcom,adsp-pil-mode" property

When this property is set, the remoteproc is used to boot the
LPASS and therefore lpass_q6ss_ahbm_clk and lpass_q6ss_ahbs_clk
clocks would be used to bring LPASS out of reset and the rest of
the lpass clocks would be controlled directly by the remoteproc.

This is a cleanup done to handle overlap of regmap of
lpasscc and lpass_aon blocks.
