lcd: mpc8xx: move mpc823-specific fb_put_byte to mpc8xx_lcd.c
Reduce the amount of platform-specific code in common/lcd.c by moving MPC823
implementation of fb_put_byte() to mpc8xx_lcd.c. Since we must also have a
default implementation for everybody else, make the remainder of the code
into a weak function.
