[PATCH V3 04/13] perf/x86/intel: Rename model-specific pebs_latency_data functions

[kan.liang@linux.intel.com]

From: Kan Liang <kan.liang@linux.intel.com>

The model-specific pebs_latency_data functions of ADL and MTL use the
"small" as a postfix to indicate the e-core. The postfix is too generic
for a model-specific function. It cannot provide useful information that
can directly map it to a specific uarch, which can facilitate the
development and maintenance.
Use the abbr of the uarch to rename the model-specific functions.
