[0/2] cxl: Dirty shutdown followups

Message

Hi,

Two followup patches to the GPF work. The first adds a
$platform/dirty_shutdown sysfs attribute - my only doubt
here is where this should be documented, and for now I just
left it in the regular ABI doc for cxl bus. The second
patch adds support emulating the set shutdown state command
for the mock device.

Patch 1 has been tested with qemu, and patch 2 is only compile
tested. Applies against the -next branch.

Thanks!
