Add Epoch Subsystem (EPSS) L3 provider support on SA8775P SoCs.

Changes since v4:
 - Added generic compatible "qcom,epss-l3-perf" changes.
 - Split the driver code into two patches, with one containing multidev
   support and other containing the compatible additions.

Changes since v3:
 - Removed epss-l3-perf generic compatible changes. These will be posted
   as separate patch until then SoC specific compatible will be used for
   probing.

Changes since v2:
 - Updated the commit text to reflect the reason for code change.
 - Added SoC-specific and generic compatible to driver match table.

Changes since v1:
 - Removed the usage of static IDs and implemented dynamic ID assignment
   for icc nodes using IDA.
 - Removed separate compatibles for cl0 and cl1. Both cl0 and cl1
   devices use the same compatible.
 - Added new generic compatible for epss-l3-perf.
