ENGR00226080 Update GC2000/GC320 AXI bus cache attribute
This patch changed the GPU AXI bus cache attribute
to improve the performance of fillrate bound case.
Here is some test result: BEFORE:AFTER (larger better)
mm06 samruai fps: 117.74:137.64
mm06 proxycon fps: 117.90:135.00
Fillrate with 1 tex: 251.3M:331.1M
Fillrate with 2 tex: 402.6M:475.4M
