serial: qcom-geni: Enable Serial on SA8255p Qualcomm platforms
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 UART baud rates, with each baud
rate represented by a performance level. The driver uses the
dev_pm_opp_set_level() API to request the desired baud rate by
specifying the performance level.
