New version of the device tree aware EMAC driver

I've made a few more tiny tweaks to BenH's rewritten device-tree based
4xx EMAC driver.  The main change is that it now no longer requires
'device_type', just 'compatible' to be set in the ZMII and MAL device
nodes when probing.  This works better with current thinking on
flattened device trees which discourages creating new device_type
values unless there is a clear use for a new device class binding.

The patch can be obtained from:

Looks like EMAC_FTR_STACR_OC_INVERT is missed in the EMAC_FTRS_POSSIBLE
(ibm_newemac/core.h)

Should be something like this:
    EMAC_FTRS_POSSIBLE    =
#ifdef CONFIG_IBM_NEW_EMAC_EMAC4
        EMAC_FTR_EMAC4 | EMAC_FTR_HAS_AXON_STACR | 
EMAC_FTR_STACR_OC_INVERT |
#endif
Thanks

In __emac_mdio_read and __emac_mdio_write functions:

+    if (!emac_has_feature(dev, EMAC_FTR_STACR_OC_INVERT))
+        r |= EMAC_STACR_OC;

should be

+    if (emac_has_feature(dev, EMAC_FTR_STACR_OC_INVERT))
+        r |= EMAC_STACR_OC;

Thanks.

With the above 2 fixes (and Marvell 88E1111 Ethernet PHY support added) 
seems to work fine on Sequoia PPC440EPx,
thanks.

Ok, I've merged those fixes.  New version of the driver coming soon.
