cxl: Adjust the startup priority of cxl_pmem to be higher than that of cxl_acpi

During the cxl_acpi probe process, it checks whether the cxl_nvb device
and driver have been attached. Currently, the startup priority of the
cxl_pmem driver is lower than that of the cxl_acpi driver. At this point,
the cxl_nvb driver has not yet been registered on the cxl_bus, causing
the attachment check to fail. This results in a failure to add the root
nvdimm bridge, leading to a cxl_acpi probe failure and ultimately
affecting the subsequent loading of cxl drivers. As a consequence, only
one mem device object exists on the cxl_bus, while the cxl_port device
objects and decoder device objects are missing.

The solution is to raise the startup priority of cxl_pmem to be higher
than that of cxl_acpi, ensuring that the cxl_pmem driver is registered
before the aforementioned attachment check occurs.
