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 !

liblitespi/spiflash: Move memspeed to specific function (spiflash_memspeed) and reduce test size.
...
On slow configurations (ex iCEBreaker / SERV CPU / 12MHz SPI Flash freq) memspeed test was
too slow (>200s to do the random test for 1MB), so reduce test size to 4KB.
This will be less accurate but will still provide representative results which
is the aim of this test.

litespi/integration: Review/Cleanup #1024 .
...
Integration from #1024 was working on some boards (ex Arty) but breaking others (ex iCEBreaker);
simplify things for now:
- Avoid duplication in spiflash_freq_init.
- Avoid passing useless SPIFLASH_LEGACY flag to software (software can detect it from csr.h).
- Only keep integration support for "legacy" PHY, others are not generic enough and can be passed with phy parameter.
