In the offloads mode, some slow path rules are added by the driver (e.g
send-to-vport), while offloaded rules are to be added from upper layers.
The slow path rules have lower priority and we don't want matching on
offloaded rules to suffer from extra steering hops related to the slow
path rules.
We use two priorities, one for offloaded rules (fast path), and one for
the control rules (slow path). To allow for that, we enable two priorities
for the FDB namespace in the FS core code.

This commit utilize the ability of ConnectX-4 to bulk read flow counters.
Few bulk counter queries could be done instead of issuing thousands of
firmware commands per second to get statistics of all flows set to HW,
such as those programmed when we offload tc filters.
Counters are stored sorted by hardware id, and queried in blocks (id +
number of counters).
Due to hardware requirement, start of block and number of counters in a
block must be four aligned.

The bcma portion of the driver has been split off into a bcma specific
driver. This has been mirrored for the platform driver. The last
references to the bcma core struct have been changed into a generic
function call. These function calls are wrappers to either the original
bcma code or new platform functions that access the same areas via MMIO.
This necessitated adding function pointers for both platform and bcma to
hide which backend is being used from the generic bgmac code.

Move the BCMA MDIO phy into a separate file, as it is very tightly
coupled with the BCMA bus. This will help with the upcoming BCMA
removal from the bgmac driver. Optimally, this should be moved into
phy drivers, but it is too tightly coupled with the bgmac driver to
effectively move it without more changes to the driver.
Note: the phy_reset was intentionally removed, as the mdio phy subsystem
automatically resets the phy if a reset function pointer is present. In
addition to the moving of the driver, this reset function is added.
