software/liblitedram: add functions to simplify read_leveling and do the test with 2 seeds.
...
Doing the test with 2 seeds prevents the test to success if previous content in DRAM was
still the expected one (ex after a sdram_cal command that succeded).

soc: change default CSR bus data-width to 32.
...
A CSR bus data-width of 32 has been validated on very various design and is
now recommended. It provides better performance without impacting resource
usage (even on iCE40).

Show speeds in bytes per second.
...
Forcing megabytes per second for everyone does not make sense.
Showing bytes per second allows to distinguish between low performance and a performance measurement bug.
Anyway previous code claims speeds were in MiB/s, they were not, actually MB/s.
