rockchip: rk3328: Add support for FriendlyARM NanoPi R2C
The NanoPi R2C is a minor variant of NanoPi R2S with the on-board NIC chip changed from rtl8211e to yt8521s, and otherwise identical to R2S. The device tree is taken from the kernel linux-next branch: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=004589ff9df5b75672a78b6c3c4cba93202b14c9 Signed-off-by: Tianling Shen <cnsztl@gmail.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
