spi: Enable SPI on SA8255p Qualcomm platforms

Praveen Talari <praveen.talari@oss.qualcomm.com> says: The Qualcomm automotive SA8255p SoC relies on firmware to configure platform resources, including clocks, interconnects and TLMM. The driver requests resources operations over SCMI using power and performance protocols. The SCMI power protocol enables or disables resources like clocks, interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs, such as resume/suspend, to control power states(on/off). The SCMI performance protocol manages SPI frequency, with each frequency rate represented by a performance level. The driver uses geni_se_set_perf_opp() API to request the desired frequency rate. As part of geni_se_set_perf_opp(), the OPP for the requested frequency is obtained using dev_pm_opp_find_freq_floor() and the performance level is set using dev_pm_opp_set_opp().
