octeontx2-af: npc: cn20k: KPM profile changes

KPU (Kangaroo Processing Unit) profiles are primarily used to set the
required packet pointers that will be used in later stages for key
generation. In the new CN20K silicon variant, a new KPM profile is
introduced alongside the existing KPU profiles.

In CN20K, a total of 16 KPUs are grouped into 8 KPM profiles. As per
the current hardware design, each KPM configuration contains a
combination of 2 KPUs:
    KPM0 = KPU0 + KPU8
    KPM1 = KPU1 + KPU9
    ...
    KPM7 = KPU7 + KPU15

This configuration enables more efficient use of KPU resources. This
patch adds support for the new KPM profile configuration.
