sh_eth: use managed device API

Browse source

Switch the driver to the managed device API by replacing ioremap() calls with
devm_ioremap_resource() (that will also result in calling request_mem_region()
which the driver forgot to do until now) and k[mz]alloc() with devm_kzalloc() --
this permits to simplify driver's probe()/remove() method cleanup. We can now
remove the ioremap() error messages since the error messages are printed by
 devm_ioremap_resource() itself. We can also remove the 'bitbang' field from
'struct sh_eth_private' as we don't need it anymore in order to free the memory
behind it...
