Laszlo Nagy c3ae609bc8 data_offload: Refactor core
Deprecate unused parameters.

Change to MEM_SIZE_LOG2, to support only power of 2 storage sizes for
now. However in the future we might want to add support for non pow2
sizes so register map is not changed.

Change transfer length to -1 value to spare logic.

Change FIFO interface to AXIS to have backpressure, this allows the
implementation of data movement logic in the storage unit and let the
FSM handle high level control an synchronization and control the storage
unit through a control interface.

Refactor FSM to have preparation states where slow storages can be
configured and started ahead of the data handling.

Make bypasss FIFO optional since in some cases causes timing failures
due the missing output register of the memory. This can be targeted in
a later commit.

Hook up underflow/overflow to regmap useful in case of external memory
where rate drops due misconfiguration can be detected.

Cleanup for verilator.

Scripting:
Add HBM and DDR external memory support using util_hbm IP
Replace asym_block_ram with util_do_ram IP

David Winter 235542cac9 data_offload: Fix support for > 4 GiB of storage
This commit changes the transfer length register to work in increments of
64 bytes and without offset. The true transfer length can now be
determined by multiplying the value of the transfer_length register with
64.
A value of zero is interpreted as a request for all available storage.

Additionally, this commit fixes an off by one issue that was discovered
during testing of the RX path.
