Subject: [PATCH v1 4/4] clk: qcom: lpasscc-sc7280: Remove qdsp6ss clock registration

The qdsp6ss memory region is being shared by ADSP remoteproc device and
lpasscc clock device, hence causing memory conflict.
As the qdsp6ss clocks are being enabled in remoteproc driver, remove the
qdsp6ss clock registration.

Fixes: 4ab43d171181 ("clk: qcom: Add lpass clock controller driver for SC7280")
