mboxd/dbus: Unconditionally send BMC EVENT to host on resume The "BMC Flash Control Lost" BMC Event (0x40) is used to signal to the host that the daemon has been suspended, such as by mboxctl --suspend. When resumed, such as by mboxctl --resume, the bit is cleared and this is again communicated to the host. When the resume command is called with clean the clearing of this bit is communicated to the host unconditionally. However when resume is called with modified we rely on the reset windows function to communicate this to the host at the same time it tells the host that the active window has been closed. However the reset windows function is only called if there was indeed an active window. This means that when resume is called with modified and there isn't an active window, the host is never told that the daemon has been resumed. Fix this by communicating the BMC event to the host unconditionally on resume irrespective of the argument.

This repo contains the protocol definition for the host to BMC mailbox communication specification which can be found in Documentation/mbox_procotol.md.
There is also a reference implementation of a BMC mailbox daemon, the details of which can be found in Documentation/mboxd.md.
Finally there is also an implementation of a mailbox daemon control program, the details of which can be found in Documentation/mboxctl.md.
