[PATCH] sched: Enable arch-specific asym packing option in scheddomain

[Diwakar Tundlam]

Add arch specific (weak) routine to set (or not set) the ASYM_PACKING
sched domain flag. This change itself does nothing, but allows archs
that require asym-packing option to set it by implementing the arch
specific routine to turn it on.
    
The weak symbol is already defined in sched_fair.c but was mis-spelled
in the header file. Fixed spelling error in the weak symbol definition.
