ibm/emac: Remove extern from function prototypes

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.

Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

drivers/net: fix up stale paths from driver reorg

The reorganization of the driver layout in drivers/net
left behind some stale paths in comments and in Kconfig
help text. Bring them up to date. No actual change to
any code takes place here.

net: fix IBM EMAC driver after rename.

In commit 9aa3283595451ca093500ff0977b106e1f465586 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*

The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors). In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.

We do not explicitly select the Kconfig dependencies, as this would force
EMAC on. Doing it in the defconfig allows more flexibility.

Tested on a canyondlands board.

ehea/ibm*: Move the IBM drivers

Move the IBM drivers into drivers/net/ethernet/ibm/ and make the
necessary Kconfig and Makefile changes.

- Renamed ibm_new_emac to emac
- Cleaned up Makefile and Kconfig options which referred to
IBM_NEW_EMAC to IBM_EMAC
- ibmlana driver is a National Semiconductor SONIC driver so
it was not moved
