cxl/pci: Clarify devm host for memdev relative setup

Browse source

It is all too easy to get confused about @dev usage in the CXL driver
stack. Before adding a new cxl_pci_probe() setup operation that has a
devm lifetime dependent on @cxlds->dev binding, but also references
@cxlmd->dev, and prints messages, rework the devm_cxl_add_memdev() and
cxl_memdev_setup_fw_upload() function signatures to make this
distinction explicit. I.e. pass in the devm context as an @host argument
rather than infer it from other objects.

This is in preparation for adding a devm_cxl_sanitize_setup_notifier().

Note the whitespace fixup near the change of the devm_cxl_add_memdev()
signature. That uncaught typo originated in the patch that added
cxl_memdev_security_init().
