[U-Boot] [PATCH V3 2/4] tools: logo: add static and unused to bmp arrays

[Che-Liang Chiou]

The generated header bmp_logo.h is useful even outside common/lcd.c for
the logo dimension.  However, the problem is, the generated bmp_logo.h
cannot be included multiple times because bmp_logo_palette[] and
bmp_logo_bitmap[] are defined in the bmp_logo.h.

We may remedy this by adding
  static __attribute__((unused))
to the array definitions so that bmp_logo.h can be included multiple
times, and these arrays is used in only one inclusion (lcd.c).
