This is an initial set of patches for the Silciom N5010 programmable
accelerated card adding support for reading out sensors.
Based on v5.13
Changes since v2:
* Removed patch 1/5 from v2 already in fpga/for-next
* Reworded commit message in patch 1/4 as per Hao's suggestion
* Added Yilun's Reviewed-by to patch 3/4 and 4/4
* Added Moritz' Acked-by to patch 3/4
* Added Moritz' Reviewed-by to patch 4/4
* Added Guenter's Reviewed-by to patch 4/4
Changes since v1:
* Commit message in patch 1 is updated with card description
* Added Hao's Acked-by to patch 1
* Patch 2 is replaced with a new patch to carry feature revision info
in struct dfl_device
* Patch 3 is updated to use feature revision from struct dfl_device
* Patch 4 from v0 is split into separate patches for hwmon and mfd

From: Martin Hundebøll <mhu@silicom.dk>
DFL device drivers have a common need for checking feature revision
information from the DFL header, as well as other common DFL information
like the already exposed feature id and type.
This patch exposes the feature revision information directly via the DFL
device data structure.
Since the DFL core code has already read the DFL header, this this patch
saves additional mmio reads from DFL device drivers too.
Signed-off-by: Martin Hundebøll <mhu@silicom.dk>

Changes since v2:
* Reworded commit message as per Hao's suggestion
Changes since v1:
* This patch replaces the previous patch 2 and exposes the feature
revision through struct dfl_device instead of a helper reading from
io-mem

The Max10 BMC on the Silicom n5010 PAC is slightly different than the
existing BMC's, so use a dedicated feature revision detect it.

Mark, if you're ok with this can you pick up patches 1/4 ("fpga: dfl:

The MFD and HWMON ones can go through the respective trees.
Thanks,
Moritz
