Many boards defining CONFIG_LCD also define CONFIG_LCD_LOGO.
Enabling CONFIG_API for such board configurations will break
compiling, e.g.:

$ ./MAKEALL TQM823L_LCD
Configuring for TQM823L_LCD - Board: TQM823L, Options: LCD,NEC_NL6448BC20
api_display.c: In function 'display_get_info':
api_display.c:40: error: 'BMP_LOGO_HEIGHT' undeclared (first use in this function)
api_display.c:40: error: (Each undeclared identifier is reported only once
api_display.c:40: error: for each function it appears in.)
make[1]: *** [api_display.o] Error 1
make: *** [api/libapi.o] Error 2

Any idea how to fix this issue?

Similar problem exists for boards using cfb_console driver, e.g. enabling
CONFIG_API breaks compiling for tqm5200 board:

$ ./MAKEALL TQM5200
Configuring for TQM5200 board...
api_display.c: In function 'display_get_info':
api_display.c:47: error: 'VIDEO_VISIBLE_COLS' undeclared (first use in this function)
api_display.c:47: error: (Each undeclared identifier is reported only once
api_display.c:47: error: for each function it appears in.)
api_display.c:48: error: 'VIDEO_VISIBLE_ROWS' undeclared (first use in this function)
make[1]: *** [api_display.o] Error 1
make: *** [api/libapi.o] Error 2

We need to resolve these issues before committing this patch, i think.

Thanks,
Anatolij
