startup sync logic rework for the new PWON button boot scheme
Previously we added logic to the MMI task to hold off PEI init until
R2D is running, and then extended that condition to wait for FCHG
init too. However, the dependencies of MMI upon R2D and FCHG don't
start until mmiInit(), and that call is driven by Switch_ON() code,
hence the wait for R2D and FCHG init can be made in that code path
instead of the MMI task. Furthermore, with our new way of signaling
PWON button boot to MMI, we need a new wait to ensure that the MMI
task is up - previously this assurance was provided by the wait for
Kp pointers to be set.
Solution: revert our previous PEI init hold-off additions to MMI,
add a new flag indicating MMI task init done, and put the combined
wait for all needed conditions into our new PWON button boot code
in power.c.
