wl18xx: add trigger command and ack event operations

Browse Source 
Add the operations that allow wlcore to trigger commands to the
firmware and acknowledge when an event has been fully received.

Allocate a private buffer to hold the maximum sized cmd. Send the
entire length of the buffer each time a command is sent to signal
EOT. Remove the previous EOT mechanism.
