[PATCH 4/4] ARM: convert PCI defines to variables

[Rob Herring <robherring2@gmail.com>]

From: Rob Herring <rob.herring@calxeda.com>

Convert PCIBIOS_MIN_IO, PCIBIOS_MIN_MEM, and PCIMEM_BASE to variables to allow
multi-platform builds. This also removes the requirement for a platform to
have a mach/hardware.h.

Signed-off-by: Rob Herring <rob.herring@calxeda.com>
