mm: reduce cache line size to 64 bytes to save memory

PD#166821: mm: reduce cache line size

If cacheline size is set to 128, then smallest kmalloc is 128, this will
cause low memory usage for slab and waste lot of memory. For ARM64,
cacheline size is hardware set to 64 bytes. Reduce to 64 bytes can improve
usage for slab. And can help to save memory.
