mlxsw: Add operations structure for bloom filter calculation
Spectrum-4 will calculate hash function for bloom filter differently from
the existing ASICs.
There are two changes:
1. Instead of using one hash function to calculate 16 bits output (CRC-16),
two functions will be used.
2. The chunks will be built differently, without padding.
As preparation for support of Spectrum-4 bloom filter, add 'ops'
structure to allow handling different calculation for different ASICs.
