Log Message:
-----------
Add support for getting and setting BBU properties related to battery
relearning. Specifically, add subcommands to mfiutil(8) which allow the
user to set the BBU and autolearn modes when the firmware supports it,
and add a subcommand which kicks off a battery relearn.

Updates the flash on the controller with the firmware stored in
.Ar file .
A reboot is required for the new firmware to take effect.
+.It Cm start learn
+Start a battery relearn.
+.It Cm bbu Ar setting Ar value
+Update battery backup unit (BBU) properties related to battery relearning.
+The following settings are configurable:
+.Bl -tag -width indent
+.It Cm learn-delay
+Add a delay to the next scheduled battery relearn event. This setting is
+given in hours and must lie in the range of 0 to 255.
+.It Cm autolearn-mode
+Enable or disable automatic periodic battery relearning.
+The setting may be set to
+.Dq enable
+or
+.Dq disable
+to respectively enable or disable the relearn cycle.
+Alternatively, a mode of 0, 1 or 2 may be given.
+Mode 0 enables periodic relearning, mode 1 disables it, and mode 2 disables
+it and logs a warning to the event log when it detects that a battery relearn
+should be performed.
+.It Cm bbu-mode
+Set the BBU's mode of operation. This setting is not supported by all BBUs.
+Where it is supported, the possible values are the integers between 1 and 5
+inclusive.
+Modes 1, 2 and 3 enable a transparent learn cycle, whereas modes 4 and 5 do not.
+The BBU's data retention time is greater when transparent learning is not used.
