common/lcd.c: cleanup use of global variables
lcd_color_fg and lcd_color_bg had to be declared in board specific code, but were not actually used there; in addition, we have getter / setter functions for these, which were not used either. Get rid of the global variables, and use the getter function where needed (so far no setter calls are needed).
