common/lcd code is full of platform-specific code and definitions, which ideally should reside with the respective driver code. Take a step towards that goal by moving platform-specific structs from lcd.h to their own header files.

The structs for the generic case (the #else for all the platform-specific cases) is retained in lcd.h as the default case.

Reduce the bitmap_plot #ifdef complexity by extracting MPC823-specific code for setting cmap into its own implementation of lcd_logo_set_cmap(), implemented in mpc8xx_lcd.c. In the MPC823 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.
