From: Srinivasa Rao Mandadapu <quic_srivasam@quicinc.com>

When this property is set, the remoteproc is used to boot the
LPASS and therefore qdsp6ss clocks would be used to bring LPASS
out of reset, hence they are directly controlled by the remoteproc.

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