85xx: Additional fixes and cleanup of MP code
* adjust __spin_table alignment to match ePAPR v0.94 spec
* loop over all cpus when determing who is up. This fixes an issue if
the "boot cpu" isn't core0. The "boot cpu" will already be in the
cpu_up_mask so there is no harm
* Added some protection in the code to ensure proper behavior. These
changes are explicitly needed but don't hurt:
- Added eieio to ensure the "hot word" of the table is written after
all other table updates have occurred.
- Added isync to ensure we don't prefetch loading of table entries
until we a released
These issues we raised by Dave Liu.
