The designware eth driver registers an mdio bus during probe, but if no
PHY is found, this bus is never removed although probe failes and the
driver is shown as not probed in the dm tree.
This later leads to errors when e.g. the mii or mdio commands try to
use available mdio buses because the mdio bus is still registered but
all corresponding data structures are invalid because probe failed.
Fix this by unregistering the mdio bus on probe failure (just as it is
unregistered in the .remove callback, too).

Some storage devices have multiple hw partitions and both address from
zero, for example eMMC.
However currently block cache invalidation only applies to block
write/erase.
This can cause a problem that data of current hw partition is cached
before switching to another hw partition. And the following read
operation of the latter hw partition will get wrong data when reading
from the addresses that have been cached previously.
To solve this problem, invalidate block cache after a successful
select_hwpart operation.
