[U-Boot] [PATCH] at91rm9200ek.h: explicitly disable D-Cache

[Andreas Bießmann]

Commit c2dd0d45540397704de9b13287417d21049d34c6 enabled D-Cache for all
arm devices explicitly. This renders at91_emac driver on at91rm9200ek
unusable.

This patch disables D-Cache for at91rm9200ek explicitly to get this
driver working again.
