We'll maybe do it but that's probably not the right time. We have to make
the picolibc switch as smooth as possible for users (and so avoid update
as much as possible).
In the long term, it would be good to provide a LiteX C SDK, so we'll make
eventual changes when doing this.

cpu/rocket/core: Remove ResetInserter on adapters.

Previously, the SoCController was only reseting the CPU, which required adding
these ResetInserters. Now that the SoCController resets both CPU and peripherals
these ResetInserters are redundant and no longer useful.

efinix: RGMII phy should be operational (no tested)

PLL infrastructure should be complete now.
We can also use DDIO input and outputs.
However, there is problem (bug) during P&R:
ERROR(1): [Line 52] Block auto_eth_tx_delayed_clk is
an output pad but sub-block 1 is not an output pad location.
Inderface Designer validation doesn't report any problem.
I have a test project with the same configuration (I compared
the reports for blocks configuration) and it works.
