[U-Boot] [PATCH v2] splash: Introduce default_splash_locations

[Anatolij Gustschin]

From: Alexey Brodkin <Alexey.Brodkin at synopsys.com>

This change introduces default_splash_locations which
simplifies splash recovery from the first partition of
USB/MMC/SATA drive.

Given usual mapping of the first partition of external media for
basic boot stuff like uImage/zImage, .dtb etc it looks quite
obvious option to put there splash.bmp as well.

Changes in v2:
 - add empty splash_source_load() if CONFIG_SPLASH_SOURCE
   is not defined (fixes building sandbox configuration)
