soc: qcom: geni-se: Enable QUPs on SA8255p Qualcomm platforms

Browse Source 
On the sa8255p platform, resources such as clocks,interconnects
and TLMM (GPIO) configurations are managed by firmware.

Use the `num_clks` field in platform data to distinguish whether
resource control is performed by firmware or directly by the driver
in linux.
