lcd: atmel: introduce lcd_logo_set_cmap
Reduce the bitmap_plot #ifdef complexity by extracting Atmel-specific code for
setting cmap into a new function lcd_logo_set_cmap(), which is implemented in
atmel_lcdfb driver and defined as part of common/lcd.c api with a weak dummy
version. In the Atmel implementation, ARRAY_SIZE(bmp_logo_palette) is
switched for BMP_LOGO_COLORS to avoid having to include bmp_logo_data.h, which
would cause a compilation error because the logo data and palette arrays would
be defined twice.
This is a step towards cleaning bitmap_plot() of platform-specific code.
