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.

RFC: json2dts: set CPU clock-frequency and SoC bus-frequency
...
FIXME: timebase-frequency isn't to be used as the raw CPU clock, so
on vexriscv we might want to re-evaluate also setting *that* to the
`CONFIG_CLOCK_FREQUENCY`. Decide whether to keep the SoC's
`bus-frequency` cell, or whether to go with the CPU's `clock-frequency`
only.
