arm64: dts: amlogic: meson-g12b: Fix L2 cache reference for S922X CPUs

The original addition of cache information for the Amlogic S922X SoC
used the wrong next-level cache node for CPU cores 100 and 101,
incorrectly referencing `l2_cache_l`. These cores actually belong to
the big cluster and should reference `l2_cache_b`. Update the device
tree accordingly.
