rainier: detect pau devices
Update the platform_ocapi structure to store Rainier platform-specific
values for detecting and resetting OpenCAPI devices via the module
I2C (PCA9553)
The unique number I2C bus ID associated to each OpenCapi device
is get from the I2C port and engine.
(De)Assert a reset and detect an OpenCapi device is available through
the I2C bus id and address.
