devlink: add timeout information to status_notify
Add a timeout element to the DEVLINK_CMD_FLASH_UPDATE_STATUS
netlink message for use by a userland utility to show that
a particular firmware flash activity may take a long but
bounded time to finish. Also add a handy helper for drivers
to make use of the new timeout value.
UI usage hints:
- if non-zero, add timeout display to the end of the status line
[component] status_msg ( Xm Ys : Am Bs )
using the timeout value for Am Bs and updating the Xm Ys
every second
- if the timeout expires while awaiting the next update,
display something like
[component] status_msg ( timeout reached : Am Bs )
- if new status notify messages are received, remove
the timeout and start over
