lcd: calculate line_length after lcd_ctrl_init()
When an LCD driver is actually driving a regular external display, e.g. an HDMI monitor, the display resolution might not be known until the display controller has initialized, i.e. during lcd_ctrl_init(). However, lcd.c calculates lcd_line_length before calling this function, thus relying on a hard-coded resolution in struct panel_info. Instead, defer this calculation until after lcd_ctrl_init() has had the chance to dynamically determine the resolution. This needs to happen before lcd_clear(), since the value is used there. grep indicates that no code outside lcd.c uses this lcd_line_length; in particular, no lcd_ctrl_init() implementations read it.
