rgb_2_rgbw_max_brightness()

void rgb_2_rgbw_max_brightness	(	uint16_t	w_color_temperature,
		uint8_t	r,
		uint8_t	g,
		uint8_t	b,
		uint8_t	r_scale,

The minimum brigthness of the RGB channels is used to set the W channel.

This will allow the max brightness of the led chipset to be used. However the leds will appear over-desaturated in this mode.

RGB(255, 255, 255) -> RGBW(255, 255, 255, 255)
RGB(1, 0, 0) -> RGBW(1, 0, 0, 1)
