Convert the incorrectly named PCIMEM_BASE to a variable called vga_base.
This removes the dependency on mach/hardware.h.

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

The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
Per Arnd Bergmann, other values are likely to be incorrect, but this commit
does not try to address that issue.

Convert pcibios_assign_all_busses from a define to inline so platforms can
control this setting.

The Marvell Discovery Duo (MV78xx0) is a family of ARM SoCs featuring
(depending on the model) one or two Feroceon CPU cores with 512K of L2
cache and VFP coprocessors running at (depending on the model) between
800 MHz and 1.2 GHz, and features a DDR2 controller, two PCIe
interfaces that can each run either in x4 or quad x1 mode, three USB
2.0 interfaces, two 3Gb/s SATA II interfaces, a SPI interface, two
TWSI interfaces, a crypto accelerator, IDMA/XOR engines, a SPI
interface, four UARTs, and depending on the model, two or four gigabit
ethernet interfaces.

This patch adds basic support for the platform, and allows booting
on the MV78x00 development board, with functional UARTs, SATA, PCIe,
GigE and USB ports.
