arm64: dts: qcom: msm8998: Fix cache nodes

The msm8998 cache nodes have some issues. First, L1 caches are described
within cpu nodes, not as separate nodes. The 'next-level-cache' property
is of course in the correct location, otherwise the cache hierarchy
walking would not work. Remove all the L1 cache nodes.

Second, 'arm,arch-cache' is not a documented compatible string. "cache"
is a sufficient compatible string for the Arm architected caches.
