sh_eth: fix TSU resource handling
commit dfe8266b8dd10e12a731c985b725fcf7f0e537f0 upstream.
When switching the driver to the managed device API, I managed to break
the case of a dual Ether devices sharing a single TSU: the 2nd Ether port
wouldn't probe. Iwamatsu-san has tried to fix this but his patch was buggy
and he then dropped the ball...
The solution is to limit calling devm_request_mem_region() to the first
of the two ports sharing the same TSU, so devm_ioremap_resource() can't
be used anymore for the TSU resource...
