Patch from Catalin Marinas

The initial code did not configure the inbound memory windows for direct
master access to the SDRAM. This patch creates a 1:1 mapping between the
Versatile/PB PCI memory windows and its SDRAM. Note that an updated FPGA
image is needed for Versatile/PB since the original windows were 1MB and
not able to cover the whole SDRAM (now extended to 256MB). The patch also
fixes the PCI IRQ mapping for slot #2.

It's pointless to include mach-types.h if you're not going to use
anything from it.  These references were removed as a result of:

grep -lr 'asm/mach-types\.h' . | xargs grep -L 'machine_is_\|MACH_TYPE_\|MACHINE_START\|machine_type'
