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

+Subject: [PATCH 114/247] clk: at91: sama7g5: remove all kernel-doc &
+ kernel-doc warnings
+
+Remove all "/**" kernel-doc markers from sama7g5.c since they are
+all internal to this driver source file only.
+This eliminates 14 warnings that were reported by the kernel test robot.
