soc: qcom: geni-se: Introduce helper APIs for performance control
The GENI Serial Engine (SE) drivers (I2C, SPI, and SERIAL) currently
manage performance levels and operating points directly. This resulting
in code duplication across drivers. such as configuring a specific level
or find and apply an OPP based on a clock frequency.
Introduce two new helper APIs, geni_se_set_perf_level() and
geni_se_set_perf_opp(), addresses this issue by providing a streamlined
method for the GENI Serial Engine (SE) drivers to find and set the OPP
based on the desired performance level, thereby eliminating redundancy.
