drivers/leds/ws2812: Fix WS2812 pixel size

Browse Source 
Although the LED might be RGB-only, the LED data is packed in a
32-bit long variable and, then, this is the default size of a LED
pixel to define the 'WS2812_RW_PIXEL_SIZE' macro. Please note that
the lower-half driver will deal with the case of the addressable
LED being 3 or 4-pixel sized.
