drivers/ipmi: Add option to wait for BMC

The BMC on Supermicro X11SSH takes 34 seconds to start the IPMI KCS, but
the default timeout of the IPMI KCS code is just 100 msec.

Add a configurable timeout option to wait for the BMC to become ready.
As it only should boot very long after power on reset, it's not a
problem on reset or warm boot.

Tested on Supermicro X11SSH.
The IPMI driver doesn't fail with a time-out any more.
