[PATCH v2 8/9] rockchip: bob: kevin: Disable dcache in SPL

This causes a hang, so disable it. Unfortunately the RAM-size fix does
not resolve the problem and I am unsure what is wrong. As soon as the
cache is enabled the board appears to hang.

Fixes: 6d8cdfd1536 ("rockchip: spl: Enable caches to speed up checksum validation")
