[U-Boot] [PATCH v2 2/7] pxa_lcd: make lcd_enable() a weak pointer

[Marek Vasut]

Dear Mike Dunn,

> Make lcd_init() a weak pointer 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.
