Subject: [PATCH v6 11/17] cxl/pci: Change find_cxl_port() 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.
