platform/x86: Update swnode graph for amd isp4

Existing swnode graph format is specific to sensor device
and is causing conflicts when accessing standard property
variables outside the sensor driver.

To address this issue, enhanced swnode graph format with
dedicated nodes for i2c and isp devices, with sensor node
added as child to i2c node. This approach allows to have
standard property variables (ex: 'clock-frequency') with
values applicable for each of the devices (sensor, i2c and
isp).

ACPI device driver_data handle is also initialized with root
camera swnode to access the property variables in the graph
in isp and i2c drivers.
