ARM: Add support for FA526 v2
Adds support for Faraday FA526 core. This core is used at least by: Cortina Systems Gemini and Centroid family Cavium Networks ECONA family Grain Media GM8120 Pixelplus ImageARM Prolific PL-1029 Faraday IP evaluation boards v2: - move TLB_BTB to separate patch - update copyrights Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt>
