ASoC: pcm3060: Add endianness flag in snd_soc_component_driver

The endianness flag is used on the CODEC side to specify an
ambivalence to endian, typically because it is lost over the hardware
link. This device receives audio over an I2S DAI and as such should
have endianness applied.

ASoC: pcm3060: Use modern ASoC DAI format terminology

As part of moving to remove the old style defines for the bus clocks update
the pcm3060 driver to use more modern terminology for clocking.

ASoC: pcm3060: Add clock select

ADC and DAC can be clocked from separate or same sources CLK1 and CLK2.
By default, ADC is clocked from CLK1, and DAC - from CLK2.

This commits allows sound cards to selest a proper clock source during
`hw_params()` via `snd_soc_dai_set_sysclk()`. It makes possible to have a
single clock source for both ADC and DAC.

ASoC: pcm3060: Rename output widgets

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

OUTL+
OUTR+
OUTL-
OUTR-

Later, in the commit [2], I added a device tree property to configure the
output as single-ended or differential. Having this property, 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 the output widgets 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.
