Fix for nodes > 0. No need to map to node and local chip id. Just pass i as
chip id. Remove unneccessary braces.
In set_capp_recoverable, return not recovered if phb not found.

Based on email from JT Kellington, Dave Larson, and Joe McGill and feedback
from Ben H.
handle_malfunction reads the bits in the malf alert reg, checks for
is_capp_recoverable, and returns 1 if recoverable. It also calls into phb3 to
put phb3 in capp error recovery state. Returns 0 if not capp recoverable and
it's a TODO to add the logic to check the other FIRs.
Don't send message when malf alert empty. Use return code -1 to tell
opal_handle_hmi to swallow the event. Also, with locking, only one thread per
core will send the message instead of all threads.

Take a lock before handle_hmi_event per Ben's suggestion. So, when we clear
events, only one thread per core will report it.

This patch implements basic framework for TOD error recovery. To start
with, this patch implements TOD sync check error recovery as an example.
Currently this patch recover from sync check error on non-master chip.
We can use same framework and recover from more TOD errors.

With new proposed change, Linux will get the HMI interrupt directly. Linux
will then invoke opal_handle_hmi to handle HMI recovery in opal. After
handling HMI errors, opal will generate an OPAL HMI event and queue it up
in opal message infrastructure so that Linux host can pull the event
and act upon it accordingly. This patch also adds new message type for
HMI event.
Changes in v2:
- Removed the token argument from opal_handle_hmi()

Move the original hmi handler to new file core/hmi.c. No functionality
change, just a code movement and variable name change.
