[PATCH v4 1/2] ARM: at91: sama5d4/dts: add #{address, size}_cells properties for macb0

[Josh Wu]

macb0 DT node can have phy child nodes, so add the #{address,
size}_cells for macb0 node.

[PATCH v4 2/2] ARM: at91: dts: sama5d4: add dts for sama5d4 xplained board

[Josh Wu]

Add at91 sama5d4 xplained board support.

Signed-off-by: Josh Wu <josh.wu@atmel.com>

Changes in v4:
- Thanks to Bo Shen to find following leds issues:
    1. the leds' label is changed in new xplained board.
    2. as piod bank is disabled in sama5d4, that will whole led driver
not work. So just disable the led which used piod.

Changes in v3:
- add phy0 child node under macb0
- rebase on top of linux next, re-formated the arch/arm/boot/dts/Makefile

Changes in v2:
- to be sorted by memory address, put the adc dt node after usart4.
