[U-Boot] [PATCH 25/27] xilfpga: Use a physical CONFIG_SYS_SDRAM_BASE

[Paul Burton]

README states that CONFIG_SYS_SDRAM_BASE should the physical base
address of SDRAM, whilst up until now various pieces of generic code
have presumed that it can be directly accessed by the CPU & MIPS has
provided a virtual address for CONFIG_SYS_SDRAM_BASE. Other generic code
expects CONFIG_SYS_SDRAM_BASE to be a physical address, which makes the
inconsistency a mess.

Now that the preceding patches have prepared us to handle using a
physical CONFIG_SYS_SDRAM_BASE, clean up the inconsistency for malta by
providing a physical CONFIG_SYS_SDRAM_BASE.

This has only been build-tested, feedback welcome.
