litedram_gen: Add ECC support on ports and add example on kcu105.

litedram_gen: Add block_until_ready port parameter to control blocking behaviour.
...
In some cases, blocking the port until controller is ready is not wanted (ex on No-CPU
config where a port is used for the memtest).

litedram_gen: Add FIFO Mode to UART (and rename serial IOs to uart).
...
It's more interesting in some design to access the UART through a FIFO like
interface than through RS232.

litedram_gen: expose a Bus Slave port instead of a CSR port.
...
The logic overhead is minimal and it makes things easier with more flexibility:
- since the main Bus is arbitrated, CPU and Bus Slave can coexist.
- integration is easier in LiteX.
- bridging to APB/AXI is easier.
