Disable D-Cache is required when booting nommu Linux kernel. (please see Linux kernel source "arch/arm/kernel/head-nommu.S")

U-Boot is enabled D-cache and I-Cache at startup. However, it does not disable D-Cache before booting nommu Linux kernel. Therefore, I call dcache_disable() when the CPU is ARMv7M to fix this problem.
