Add back a slightly modified version of the lowlevel settings which
where removed with r46920.
In compare to the old lowlevel settings, the B43c tone is added to
tone_adsl_b and tone_adsl_bv.
If an unsupported tone value is used, the auto probing mode is used, in
compare to the fallback to tone_adsl_av and tone_vdsl_av with the old
lowlevel settings.

I've done some tests to see in which situations the tone setting is
required. In cases no tone is specified, the tone is used according to
the loaded firmware or set by the loaded firmware.
Using a device with the hybrid set to POTS (Annex A) on a Deutsche
Telekom VDSL2 line which requires the B43 tone, I made the following
observations:
annex setting firmware tone setting result
-------------------------------------------------------
annex a adsl-a.bin no tone no sync
annex a adsl-a.bin b sync
annex a adsl-b.bin no tone sync
no annex adsl-a.bin no tone no sync
no annex adsl-a.bin b sync
no annex adsl-b.bin no tone sync
I would vote for using 'auto' for the initial config here as well. I
would expect that people who are using an Annex A device in an Annex B
network know how to set the correct tone value.
