[PATCH ndctl] cxl: Add list all option to the cxl command

[sunfishho12@gmail.com]

From: Matthew Ho <sunfishho12@gmail.com>

This adds a new subcommand cxl list --all, which is equivalent to cxl list -MBPEDTHIiu. This addition makes it easier to list all the CXL devices at once, as one does not need to append a subcommand for each device. --all is also easier to remember than -MBPEDTHIiu. When region support is added, this will be updated to include it.
