phy/lpddr5/sim: fix SimLogger timestamps
...
Timestamps were completely wrong for WCK as it is disabled
until the first write command and has varying frequency.
Now we use another clock which is always on to calculate time.

litedram_gen: Add Auto-Flush to UART in FIFO mode.
...
In FIFO mode, backpressure is propagated to the UART and would stall the CPU
when the UART is not accepting data. Enable Auto-Flush on the UART to allow
DRAM initialization when the UART is not ready.

litedram_gen: Block accesses on User ports until the controller is successfully initialized.
...
This is convenient on some systems to decouple DRAM accesses from the init status reported by
the cores. User ports can still try to write/read data to the ports, the controlled will
just block the transfers and release them when it will be initialized.
