ice: Refactor FW data type and fix bitmap casting issue
[ Upstream commit 817b18965b58a6e5fb6ce97abf01b03a205a6aea ]
According to the datasheet, the recipe association data is an 8-byte
little-endian value. It is described as 'Bitmap of the recipe indexes
associated with this profile', it is from 24 to 31 byte area in FW.
Therefore, it is defined to '__le64 recipe_assoc' in struct
ice_aqc_recipe_to_profile. And then fix the bitmap casting issue, as we
must never ever use castings for bitmap type.
Fixes: 1e0f9881ef79 ("ice: Flesh out implementation of support for SRIOV on bonded interface")
