clk: qcom: lpasscc-sc7280: Skip qdsp6ss clock registration

The qdsp6ss memory region is being shared by ADSP remoteproc device and
lpasscc clock device, hence causing memory conflict.
To avoid this, when qdsp6ss clocks are being enabled in remoteproc driver,
skip qdsp6ss clock registration if "qcom,adsp-pil-mode" is enabled and
also assign max_register value.
