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.

When printing the string "\r\n" to the framebuffer console, the first
character of the current line was being replaced with a space. The "boot"
prompt would become the "oot" prompt. This change makes the cursor
non-destructive so that no matter where it goes on its way to where it's
supposed to be, the end result is that the cursor is where it's supposed to
be with the other text preserved.

While video_font.h is useful even without referencing the font data, it
is not possible to be included multiple times because it defines font
data array right in the header.
This patch splits the font data array into video_font_data.h and so now
video_font.h can be included multiple times. This at least solves the
code duplication in board/mcc200/lcd.c.

The generated header bmp_logo.h is useful even outside common/lcd.c for

cannot be included multiple times because bmp_logo_palette[] and
bmp_logo_bitmap[] are defined in the bmp_logo.h.
This patch fixes this by defining these arrays in another header
bmp_logo_data.h and in bmp_logo.h only declaring these arrays.
