[ARM] 3113/1: PXA: Allow machines to override (and also reuse) pxa pm functions
Patch from Richard Purdie Update the PXA pm.c file to allow machines (such as the Sharp Zaurus) to override the standard pm functions but reuse/wrap them where needed. The init call is made slightly earlier to give machine code an init level to override them in removing any race.
