Valentine Barshak 9ba379ade7 ARM: cpu: Add ARMv7 barrier operations support
This enables ARMv7 barrier operations support when
march=armv7-a is enabled.

Using CP15 barriers causes U-Boot bootm command crash when
transferring control to the loaded image on Renesas R8A7794 Cortex A7 CPU.
Using ARMv7 barrier operations instead of the deprecated CP15 barriers
helps to avoid these issues.
