at91: add kernel support for sama7g5 soc
Add kernel support for SAMA7G5 by back-porting mainline kernel patches. Among SAMA7G5 features could be remembered: - ARM Cortex-A7 - double data rate multi-port dynamic RAM controller supporting DDR2, DDR3, DDR3L, LPDDR2, LPDDR3 up to 533MHz - peripherals for audio, video processing - 1 gigabit + 1 megabit Ethernet controllers - 6 CAN controllers - trust zone support - DVFS for CPU - criptography IPs Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com>
