arm64: dts: amlogic: Add cache information to the Amlogic S922X SoC

As per S922X datasheet add missing cache information to the Amlogic
S922X SoC.

- Each Cortex-A53 core has 32 KB of instruction cache and
	32 KB of L1 data cache available.
- Each Cortex-A73 core has 64 KB of L1 instruction cache and
	64 KB of L1 data cache available.
- The little (A53) cluster has 256 KB of unified L2 cache available.
- The big (A73) cluster has 1 MB of unified L2 cache available.

Cache memory significantly reduces the time it takes for the CPU
to access data and instructions, leading to faster program execution
and overall system responsiveness.
