Subject: [PATCH 2/2] ASoC: pcm3060: Rename output widgets

In the initial commit [1], I added differential outputs of the codec as
separate `+` and `-` widgets:

OUTL+
OUTR+
OUTL-
OUTR-

Later, in the commit [2], I added a control to switch the outputs between
differential and single-ended modes. Having this control, the `+` and `-`
separation in widgets seems for me confusing. There are no functional
benefits in such separation, so I find reasonable to get rid of it:

OUTL
OUTR

The new naming is more friendly for sound cards, and is better aligned with
other codec drivers in kernel.

Renaming outputs now should not be a problem from the backwards-
compatibility perspective, as the driver for PCM3060 is added into the
mainline very recently, and did not yet appear in any releases.

[1] commit 6ee47d4a8dac ("ASoC: pcm3060: Add codec driver")
[2] commit c33260d09337 ("ASoC: pcm3060: Add control for differential
    output")
