tools/testing/cxl: Add partition support
In support of testing DPA allocation mechanisms in the CXL core, the
cxl_test environment needs to support establishing and retrieving the
'pmem partition boundary.
Replace the platform_device_add_resources() method for delineating DPA
within an endpoint with an emulated DEV_SIZE amount of partitionable
capacity. Set DEV_SIZE such that an endpoint has enough capacity to
simultaneously participate in 8 distinct regions.
