[U-Boot] [PATCH 2/8] pxa_lcd: make lcd_enable() a weak pointer

[Mike Dunn]

Make lcd_init() a weak pointer aliased to the current (and currently empty)
lcd_init(), so that boards can overload it if necessary.  The palmtreo680 board
needs to wiggle some gpios and configure the pwm controller in order to get the
lcd and its backlight working.
