[PATCH v5 07/26] cxl/acpi: Moving add_host_bridge_uport() around

[Terry Bowman <terry.bowman@amd.com>]

From: Robert Richter <rrichter@amd.com>

Just moving code to reorder functions to later share cxl_get_chbs()
with add_host_bridge_uport().

This makes changes in the next patch visible. No other changes at all.
