Supersedes #103

The linker script has L1 address ORIGIN set to 0x10000004 even through
in hardware it is set to 0x10000000. However the testbench assumes 64b
alignment to initialize the L1. Thus, the data was shifted by 32b in the
simulation. While the AXI bursts are set to 64b, the misalignment needs
to be handled coming from the linker script.
Being unnecessarily unpacked, it was not compatible with other systems (like Cheshire)
It created problems in routing of requests through peripheral interconnect
… configurations based on WidePortShouldBeEnabled. Update AXI request/response handling and introduce a multiplexer for merging cluster bus and DMA narrow master requests. Enhance isolation and CDC instantiation for wide port scenarios.

…arameters

- Update HCI interface parameter structure to correctly propagate the
FIFO depth parameter to both the interconnect and the HWPE (Neureka)
- Increase the FIFO depth parameter from 0 to 2 to fix the combinational
loop due to iDMA being able to read+write from+to TCDM with its 2
backend
- Bump versions of HCI and Neureka in bender for updated parameter
structure
