add at least icache support for at91 based boards. This speeds up NOR flash access on an at91sam9g15 based board from 15.2 seconds reading 8 MiB from a SPI NOR flash to 5.7 seconds.

removed the dcache enable in the gurnard board. Comment says that enabling dcache breaks Ethernet MAC ... why is it then enabled?
@Simon: If you need dache enabled for the gurnard board, arch/arm/mach-at91/arm926ejs/cache.c is the correct place for doing this, I think. Please add there the common functions needed for dcache support on at91 plattforms and undef in the gurnard board configuration CONFIG_SYS_DCACHE_OFF.
