[PATCH v3 38/39] nouveau-dbg: fixup lost prdbgs

[Jim Cromie]

Undo the 1-line change that reduced count of prdbgs from 632 to 119.

ie: s/NV_SUBDEV_DBG_##l/NV_DBG_##l/

So heres what happened: new symbol is 15 (or 10), and fails this macro
test, so gets compiled out, and the dev_dbg is excluded.

        if (CONFIG_NOUVEAU_DEBUG >= (l) && _subdev->debug >= (l))       \
                dev_dbg(_subdev->device->dev, "%s: "f, _subdev->name, ##a); \

I could hack this, by doing (l + base), but base is pretty distant.

OTOH, the whole CONFIG_NOUVEAU_DEBUG check could be reworked; given
that trace is minumum recommended, theres not that many callsites
elided (SPAM only iirc) at compile-time, and dyndbg means keeping them
has "zero" run=cost (and 56 bytes per).  So this config item doesnt do
much when DRM_USE_DYNAMIC_DEBUG=y.

So this is a useful place to stop and look around, try to guess which
trail to take..
