[PATCH 2/3] cxlflash: Add device dependent flags

[Uma Krishnan]

Device dependent flags are needed to support functions that are
specific to a particular device.

One such case is - some CXL Flash cards need to be notified of
device shutdown. For other CXL devices, this feature does not prove
to be useful yet. Such distinct features need to be identified in
the driver to bypass or invoke specific functionality.

In this patch, a member 'flags' has been added to device dependent
values. These flags will be used and expanded in the future to
support various device specific functions.
