Add GDSCs in lpass_cc_sc7280_desc struct.
When qcom,adsp-pil-mode is enabled, GDSCs required to solve
dependencies in lpass_audiocc probe().

From: Srinivasa Rao Mandadapu <[email protected]>
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.

From: Srinivasa Rao Mandadapu <[email protected]>
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.
