[PULL 03/13] hw/ppc/sam460ex: Support short options for adding drives

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: BALATON Zoltan <balaton@eik.bme.hu>

Having to use -drive if=none,... and -device ide-[cd,hd] is
inconvenient. Add support for shorter convenience options such as
-cdrom and -drive media=disk. Also adjust two nearby comments for code
style.
