[PATCH] Fix pcibios_setup

[Matthew Wilcox <matthew@wil.cx>]

pcibios_setup() should return NULL if it handled a parameter.  Since ia64
handles no parameters, it should return the string that was passed in,
not NULL.  This brings ia64 into line with all other architectures that
handle no parameters.
