[yocto] [meta-rockchip][PATCH] u-boot-rockchip: fix for binutils-2.28

[Trevor Woerner]

openembedded-core updated bintuils from 2.27 to 2.28 which causes u-boot to
fail to compile:

	arm-oe-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try linking with -N

Building with -N does fix the issue, so this patch simply adds that flag to
the build so it succeeds.

This has been build-tested, as well as run-tested on the firefly.
