We have to wait until the controller is no longer busy before we announce
that we're done. Just waiting for the first interrupt isn't enough, because
that's often just an error indicator and the controller still has to stop.

Supports turning system on and off via power button.
Also added 'powerbtn' command, which sends a power button press of the
specified duration, and deprecated the 'x86power s0' command, since
pressing the power button is a more correct way of powering on/off the
system.
Note that current coreboot doesn't seem to boot reliably; when it
fails, the x86 asks for S5 and then S0 a second later. It boots about
every 3rd try. No indication this is due to the EC; the EC just was
ignoring these requests until this CL.

Original code tests SND bit, but it is not reliable to indicate the
SERIRQ frame has been sent out because the EC always clears it
immediately. Unfortunately the SIRQRIS is always asserted in
continuous mode so that we cannot rely on it.
So, the udelay(4us) method is the best way we can use now.
Note: the quiet mode? Forget it. My EC never sends out further frames
after the first has been sent.
