From: Peng Fan <peng.fan@nxp.com>

A72 Cluster has 48KB Icache, 32KB Dcache and 1MB L2 Cache
 - ICache is 3-way set-associative
 - Dcache is 2-way set-associative
 - Line size are 64bytes

So correct the cache-sets info.

Fixes: d548c217c6a3c ("arm64: dts: add QorIQ LX2160A SoC support")

V1:
 I am not sure whether this is intentional or not using the original cache
 sets value. If the original value is correct, please drop this patch.
