mx6sabresd: Avoid hang when HDMI cable is not connected
Since commit d9b894603 (mx6sabresd: Add LVDS splash screen support) the
following hang happens if the HDMI cable is not connected or the 'panel'
variable is not set:
U-Boot 2013.10-rc2-12978-g47ac53d-dirty (Sep 11 2013 - 15:07:38)
CPU: Freescale i.MX6Q rev1.2 at 792 MHz
Reset cause: POR
Board: MX6-SabreSD
DRAM: 1 GiB
MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2
...
Provide a check to 'dev->detect' in order to prevent the hang.
