poplar: enable Ethernet driver support
The 'phy' reset of gmac device in kernel device tree is not generic enough for u-boot to use, so we need to overwrite the 'resets' property as needed. With this device tree fixup and poplar_defconfig changes, Ethernet starts working on Poplar board. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
