[PATCH 0/7] cxl: Add CXL type2 accelerator support for cxl_test

[Dave Jiang <dave.jiang@intel.com>]

The series is based on v7.0-rc7 with Alejandro's type2 series [1] and
with Dan's follow on series [2].

Series adds a 'type2_test' module parameter where it setup a mock type2
hierarchy with a mock type2 accelerator device directly under a root
port that has an auto region setup.

It also includes a CXL fix that was encountered when running tests with
the new code.
