Subject: [PATCH v2 08/14] cxl/pci: Change find_cxl_ports() to non-static
CXL PCIe port protocol error support will be added in the future. This
requires searching for a CXL PCIe port device in the CXL topology as
provided by find_cxl_port(). But, find_cxl_port() is defined static
and as a result is not callable outside of this source file.
Update the find_cxl_port() declaration to be non-static.
