Replace the cache related CONFIG flags with more meaningful names. Following are the changes: CONFIG_L2_OFF -> CONFIG_SYS_L2CACHE_OFF CONFIG_SYS_NO_ICACHE -> CONFIG_SYS_ICACHE_OFF CONFIG_SYS_NO_DCACHE -> CONFIG_SYS_DCACHE_OFF Signed-off-by: Aneesh V <aneesh@ti.com> V2: * Changed CONFIG_L2_OFF -> CONFIG_SYS_NO_L2CACHE V4: * Changed all three flags to the final names suggested as above and accordingly changed the commit message
