[PATCH v2 099/148] net/ice/base: temporary workaround for E830 signed package support

[Anatoly Burakov]

From: Ian Stokes <ian.stokes at intel.com>

Add a workaround to deal with a signed package issue where the following
sections are in the DDP OS package, but the FW does not support.

To allow the package and FW to work togther properly, skip downloading
the unsupported sections by forcing the number of buffers in the
E830 reference signature segment to be 1 instead of 3. That will bypass
the download of the two buffers that contain the unsupported sections.
