Remove #ifdef around 'enum EDSR_BIT' and 'enum GECMR_BIT', replacing it with the
comments on which SoCs these registers exist.
SH7757 also has EDSR, so add a comment about it to 'enum EDSR_BIT'.

Conflicts:
net/mac80211/sta_info.c
net/wireless/core.h
Two minor conflicts in wireless. Overlapping additions of extern
declarations in net/wireless/core.h and a bug fix overlapping with
the addition of a boolean parameter to __ieee80211_key_free().

The 'link' field of 'struct sh_eth_private' has type 'enum phy_state' while the
'link' field of 'struct phy_device' is merely *int* (having values 0 and 1) and
the former field gets assigned from the latter. Make the field match, getting
rid of incorrectly used PHY_DOWN value in assignments/comparisons.

The driver's header file contains initialized register offset tables which (as
any data definitions), of course, have no business being there. Move them to
the driver's body, somewhat beautifying the initializers, while at it...

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...

sh_mdio_init() allocates pointer to 'struct bb_info' but only stores it locally,
so that sh_mdio_release() can't free it on driver unload. Add the pointer to
'struct bb_info' to 'struct sh_eth_private', so that sh_mdio_init() can save
'bitbang' variable for sh_mdio_release() to be able to free it later...

of skb->data. Seems that there is no corresponding dmap_unmap_single()
calls for the moment in this driver.

When this GETHER controller received a large frame (about 1800 bytes
or more), skb_over_panic() happened. This is because the previous
driver set the RFLR to 0x1000 (4096 bytes) and the skb allocate size
is smaller than 4096 bytes. So, the controller accepted such a frame.
The controller can discard a large frame by the RFLR setting.
So, the patch modifies the value of RFLR to mtu + ETH_HLEN +
VLAN_HLEN + ETH_FCS_LEN.
