Move registration of lpass_q6ss_ahbm_clk and lpass_q6ss_ahbs_clk to
lpass_aon_cc_sc7280_probe and register them only if "qcom,adsp-pil-mode"
is enabled in the lpass_aon DT node.

Your Signed-off-by should be last. If Taniya's SoB is present then I'd
expect a Co-developed-by tag as well, or the author should be Taniya.
Either way Taniya's SoB should be first.
