Subject: [PATCH] ARM: dts: at91: sama5d4: add labels to soc dtsi for derivative boards

This adds labels to commonly used device-tree nodes so that derivative
boards can avoid ahb/apb hierarchy.

Hello,

This was already done for SoC sama5d3 and sam9x5, in commit:
"fc37204432d" ("ARM: dts: at91: add labels to soc dtsi for derivative boards")

This commit will do basically the same thing for sama5d4 SoC.

Based on top of at91-next branch of at91.git

Thanks.
