cpus: remove common cpu variants/extensions definition and simplify variant check.
...
Having common cpu variants/extensions has no real additional value since we are supporting
very various CPUs where minimal/standard/full have different meanings. Checking against
common variants/extensions has also cause more issues recently when adding new CPUs than
the additional value it was supported to provide.
So let's just simplify things: a CPU provide the supported variants and we just check
against that.

tools: add litex_crossover to be able to use lxterm (and serialboot) over a crossover UART (bridged over UART/Ethernet/PCIe/USB, etc...).
...
This is still a proof of concept but can be used/tested with:
lxsim --with-etherbone --uart-name=crossover --csr-csv=csr.csv
lxserver --udp --udp-ip=192.168.1.51
lxcrossover (will indicate the virtual_tty)
lxterm virtual_tty

litex_sim: override uart_name to sim only for serial.
...
Using uart_name=crossover is useful to simulate crossover mode.

Extend I2S capabilities
...
This commit:
* adds the support for I2S standard mode,
* extends I2S left justified mode,
* allows to configure sample size for tx/rx in 1-32 bits range,
* implements I2S master mode,
* allows to concatenate channels or used the padded mode.
This required to rework the FSM.
