Merge series "ASoC: Intel: bytcr_rt5640: Fix HP ElitePad 1000 G2 audio routing" from Hans de Goede <[email protected]>:

Changes in v2:
- Only set lineout_string if BYT_RT5640_LINEOUT is set, since
  BYT_RT5640_LINEOUT_AS_HP2 only works if the lineout is enabled in
  the first place

Original cover-letter:

The HP Elitepad 1000 G2 has 2 headset jacks:

1. on the dock which uses the output of the codecs built-in HP-amp +
the standard IN2 input which is always used with the headset-jack.

2. on the tablet itself, this uses the line-out of the codec, combined
with an external HP-amp + IN1 for the headset-mic.

This series adds support for this, resolving:
https://bugzilla.kernel.org/show_bug.cgi?id=213415

Note this series does not add jack-detect support. I plan to add that
with a follow-up series when I can make some time to implement that.

Regards,

Hans
