[PATCH v2] accel/rocket: request the core clocks by name

[Igor Paunovic]

A correction to my own message above, before it stands uncorrected in
the archive.

I wrote that the two test reports cover "the two NanoPC-T6 variants
besides my own board". That is wrong, and it misattributes Sidong's
work. Sidong tested on a Radxa ROCK 5B+, not on a NanoPC-T6:

Diederik's report is the one covering the two NanoPC-T6 variants. So the
coverage is three boards besides mine, on three different designs:

  Tested-by: Sidong Yang <sidong.yang at furiosa.ai>        # Radxa ROCK 5B+
  Tested-by: Diederik de Haas <diederik at cknow-tech.com>  # NanoPC-T6 LTS, NanoPC-T6 Plus

Apologies to Sidong for getting his hardware wrong - his report was the
more thorough of the two, with clk_summary before and after, 90 runtime
PM cycles across the three cores, and bit-exact inference results, and
it deserved to be quoted accurately.

Nothing else in that message changes.
