There is no need to print an error message when cpu_eth_init() fails because
net/eth.c already prints it.
In order to simplify the code, just return the value from cpu_eth_init(bis)
directly.

Currently HDMI splash screen is selected by default on mx6sabresd boards.
As LVDS is also enabled, this causes incorrect colors to be displayed im the
LVDS panel.
Fix this by selecting the LVDS panel as the default splash output and only keep
HDMI or LVDS turned on at the same time.

Add support for displaying U-boot splashscreen on it.
By default, HDMI splash is selected.
In order to use splash via LVDS, do the following in the U-boot prompt:
setenv panel Hannstar-XGA

The SabreSD platform is available with i.MX6Q or i.MX6DL. This patch adds the
support of the i.MX6DL. The config file and the board directory are renamed
to remove the reference to the MX6Q.
