Missing function declaration in rk_hdmi.h

[offsides]

The file drivers/video/rockchip/hdmi/rk_hdmi.h is missing the declaration for hdmi_init_lcdc (from drivers/video/rockchip/hdmi/hdmi-lcdc.c). Adding the following line to rk_hdmi.h resolves the issue:

extern void hdmi_init_lcdc(struct rk29fb_screen *screen, struct rk29lcd_info *lcd_info);
