Currently, exynos FIMD driver is being used to support only TIZEN LOGOs.
In order to get LCD console, we need to enable half word swap feature
of FIMD and use 16 BPP.
LCD console and proprietary Logo cannot be used simultaneously.
We use "logo_on" field inside vidinfo_t structure to decide whether
user wants Logo or Console.
Define CONFIG_CMD_BMP and make logo_on = 1 to get Logo on screen.
Use logo_on = 0 to get output console on LCD.

Changes in V2:
-- Use CONFIG_CMD_BMP instead of CONFIG_TIZEN to distinguish
between Proprietary logo support and LCD console support.
Changes in V3:
-- Create and use new config CONFIG_EXYNOS_LOGO instead of using
CONFIG_CMD_BMP
Changes in V4:
-- Remove #ifdef CONFIG_EXYNOS_LOGO, instead use logo_on field
to add LCD console support.
Changes in V5:
-- Remove dummy definition for bmp_display. Instead, place the call to
bmp_display inside #ifdef CONFIG_CMD_BMP
-- Added changelog in commit message.
Changes in V6:
-- Moved changelog to proper position
