Errata A-007273 (For FMan V3 devices only):
FMan soft reset is not finished properly if one
of the Ethernet MAC clocks is disabled
Workaround:
Re-enable all disabled MAC clocks through the DCFG_CCSR_DEVDISR2
register prior to issuing an FMAN soft reset.
Re-disable the MAC clocks after the FMAN soft reset is done.

Currently, in a case of error, dev_err is using fman->dev
before its initialization and "(NULL device *)" is printed.
This patch fixes this issue.

Add the Data Path Acceleration Architecture Frame Manger Driver.
The FMan embeds a series of hardware blocks that implement a group
of Ethernet interfaces. This patch adds The FMan configuration,
initialization and runtime control routines.
The FMan driver supports several hardware versions
differentiated by things like:
- Different type of MACs
- Number of MAC and ports
- Available resources
- Different hardware errata
