Previously, the call to draw_logo() was happening irrespective
of whether we have selected logo or LCD console.
With this patch we call draw_logo() only when CONFIG_CMD_BMP is selected.
This would even fix the following compilation warning:
exynos_fb.c: In function 'draw_logo':
exynos_fb.c:74:8: warning: variable 'addr' set but not used
[-Wunused-but-set-variable]
exynos_fb.c:73:9: warning: variable 'y' set but not used
[-Wunused-but-set-variable]

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.

Several DIU registers were being initialized either unnecessarily or to
wrong values.
1) All interrupts were enabled even though there's no interrupt handler.
Interrupts were left enabled when booting Linux.
2) Don't configure a dummy area descriptor, since we don't support ADs
in U-Boot.
3) Don't configure any write-back buffer registers, since we don't use
that mode.
4) The default values for the THRESHOLDS, SYN_POL, and PLUT registers
should be used, so don't touch those registers either.
