soc: qcom: geni-se: Introduce helper API for resource initialization
The GENI Serial Engine drivers (I2C, SPI, and SERIAL) currently duplicate
code for initializing shared resources such as clocks and interconnect
paths.
Introduce a new helper API, geni_se_resources_init(), to centralize this
initialization logic, improving modularity and simplifying the probe
function.
