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 CC: Christoph Raisch <raisch@de.ibm.com> CC: Santiago Leon <santil@linux.vnet.ibm.com> CC: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: David Gibson <dwg@au1.ibm.com> CC: Kyle Lucke <klucke@us.ibm.com> CC: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
