spi: qcom-geni: trace: Add trace events for Qualcomm GENI SPI

Browse Source 
Add tracepoint support to the Qualcomm GENI SPI driver to provide
runtime visibility into driver behavior without requiring invasive debug
patches.

The trace events cover clock and setup parameter configuration,
transfer metadata, interrupt status to be making it easier to diagnose
communication issues in the field..
