[PATCH] ppc32: make usage of CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT consistent

Andrew,

CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT are not currently consistently used 
in the code base.  Fixed up the usage such that CONFIG_PTE_64BIT is used 
when we have a 64-bit PTE regardless of physical address width.  
CONFIG_PHYS_64BIT is used if the physical address width is larger than 
32-bits, regardless of PTE size.

These changes required a few sub-arch specific ifdef's to be fixed and the 
introduction of a physical address format string.
