From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit f9a531d6731d74f1e24298d9641c2dc1fef2631b upstream.

After the Ether platform data is fixed, the driver probe() method would
still fail since the 'struct sh_eth_cpu_data' corresponding to SH771x
indicates the presence of TSU but the memory resource for it is absent.
Add the missing TSU resource to both Ether devices and fix the harmless
off-by-one error in the main memory resources, while at it...

Fixes: 4986b996882d ("net: sh_eth: remove the SH_TSU_ADDR")
