MAINTAINERS: split Renesas Ethernet drivers entry

Since the Renesas Ethernet Switch driver was added by Yoshihiro Shimoda,
I started receiving the patches to review for it -- which I was unable to
do, as I don't know this hardware and don't even have the manuals for it.
Fortunately, Shimoda-san has volunteered to be a reviewer for this new
driver, thus let's now split the single entry into 3 per-driver entries,
each with its own reviewer...
