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.

cpu/rocket: include core count as per-variant parameter
...
Repurpose (and rename to `CPU_SIZE_PARAMS`) the current
`AXI_DATA_WIDTHS` array. In addition to axi widths for
mem and mmio ports, also include each variant's number
of cores, to facilitate dynamically generated per-core
signals.

Add an hacked no we memory for Efinix

Efinity synthesizer cannot infer RAM blocks with write enable.
In order to workaround this (at least for the Litex SoC intergrated
RAM/ROM) a dirty modified Memory class has been created.
This class needs to be rewrite !
