[Skiboot] [PATCH] hw/phb4: Use standard MIN/MAX macro definitions

[Jordan Niethe]

The max() macro definition actually returns the smallest value.  Macro
definitions for MIN and MAX are already provided in skiboot.h.  Remove
the redundant/incorrect versions here and switch to using the standard
ones.
