Small change (dereferencing pointer instead of double pointer) to avoid snmpget (+walk) to collapse

See merge request !15

Not supported anymore

Display the correct name for disabled state,
avoid buffer overflow in pp_printf,
factorize pointer use.

The software has been slightly changed so that it also supports the streamers-on-spec_trigger-distribution testbench.
Now, both wrc_core and streamers-on-spec_trigger-distribution testbenches are supported.

The following files are changed to ensure the functionality of the WRPC
testbench located in "testbench/wrc_core" folder of the wrpc-core repository:
- wrc_main_sim.c
- arch/risc-v/crt0.S
- arch/risc-v/crt0.h
- dev/endpoint.c
- configs/wrpc_sim_riscv_defconfig

Before compiling wrpc-sw for simulation, choose wrpc_sim_riscv_defconfig configuration.

In endpoint.c, delay function is commented out in the case of simulation.
In wrc_main_sim.c, passing information from the testbench to risc-v's software
is fixed and mini-NIC component is initialized correctly. Also, now the program
doesn't print the error message when the Rx FIFO of mini-NIC is empty, but
waits until there is something in the Rx FIFO, and then continues with checking
the correctness of the received frame.

- should fix a rare phase error 'aliasing' issue where the phase error value flips between two extremes, resulting in slow (or never-happening) lock.
- added lock time statistics to 'pll stat' command

Now enabled on wr2rf

to avoid errors while converting bin to vhd

The enable subcommand is renamed to unfreeze

But disabled by default

So that it is easier to spot which configuration box
should be used to enable a particular command

variable DAC_BITS for main PLL
