octeontx2-af: add support for custom KPU entries
Add ability to load a set of custom KPU entries. This allows for flexible support for custom protocol parsing. AF driver will attempt to load the profile and verify if it can fit hardware capabilities. If not, it will revert to the built-in profile. Next it will replace the first KPU_MAX_CST_LT (2) entries in each KPU in default profile with entries read from the profile image. The built-in profile should always contain KPU_MAX_CSR_LT first no-match entries and AF driver will disable those in the KPU unless custom profile is loaded. Profile file contains also a list of default protocol overrides to allow for custom protocols to be used there.
