arm64: dts: amlogic: Add cache information to the Amlogic A1 SoC

Browse Source 
As per the A1 datasheet add missing cache information to the Amlogic A1
SoC.

- Each Cortex-A53 core has 32KB of L1 instruction cache available and
	32KB of L1 data cache available.
- Along with 512KB Unified L2 cache.

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.
