cxl/port: Introduce port_to_host() helper
In CXL subsystem, a port has its own host device for the port creation
and removal. The host of CXL root and all the first level ports is the
platform firmware device, the host of other ports is their parent port's
device. Create this new helper to much easier to get the host of a cxl
port.
Introduce port_to_host() and use it to replace all places where using
open coded to get the host of a port.
Remove endpoint_host() as its functionality can be replaced by
port_to_host().
