Since the code for multicast filtering has been dropped, the function
hif_set_data_filtering() is only called to disable multicast filtering.
In fact, the multicast filtering is already disabled by default. So,
this function is useless and can be dropped.

The device allows to filter multicast frames. The driver has the
necessary code to take advantage of this feature. However, some bugs
has been reported on this feature. So, it was temporary disabled.

Finally, the things work well as-is for more than one year now. So there
is no plan to enable this feature in near future.

Since we dislike to maintain dead code, drop it.

The Secure Link (slk) feature allows to encrypt (and authenticate) the
traffic between the host and the device. The official implementation of
this feature relies on mbedTLS. For that reason, this implementation is
not included in the current driver. To be included, the implementation
has to rely on kernel crypto API instead of mbedTLS.

So, for now, the driver contained stub functions waiting for the new
implementation based on kernel crypto API.

This new implementation represent a bunch of work and it is unlikely to
be done in near future.  Moreover, we strongly dislike to maintain
useless code. So, drop all the code related to secure link.

Whoever wants to implement secure link should revert this patch before
starting to work on it.

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().

struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).

It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.

To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.
