From: Pranav Madhu <pranav.ma...@arm.com>
The SGI-575 platform includes two clusters with four single-thread CPUs.
Each of the CPUs include 64KB L1 Data cache, 64KB L1 Instruction cache
and 512KB L2 cache. Each cluster includes a 2MB L3 cache. Add PPTT table
for SGI-575 platform with this information.
