spi-geni-qcom: Add shared_ee dtsi property for spi driver

When shared_ee dtsi flag is set then don't depend on the
shared_se checks in prepare/unprepare transfer
hardware and runtime resume/suspend APIs of spi driver. Also
use runtime resume/suspend calls from prepare/unprepare
message so that dual EE use case for spi will not be effected.

This change is to help in the cases where spi can be used
from secure and non-secure use cases. Spi framework
calls unprepare transfer hardware from a kthread after the
spi_pump_message call is completed and by that time spi driver
might be getting used from a secure use case and at the same time
unprepare transfer hardware is selecting the pinctrl to sleep state.
