[PATCH] linux/stmmac.h: include <linux/platform_device.h> to remove compilation warning.

stmmac.h uses struct platform_device and doesn't include
<linux/platform_device.h>. And so we get following compilation warning while
using this file:
	warning: ‘struct platform_device’ declared inside parameter list

This patch includes <linux/platform_device.h> in stmmac.h to remove this warning
