Integrate tas2781 configs for Lenovo Laptops. All of the tas2781s in the laptop will be aggregated as one audio device. The code support realtek as the primary codec. Rename "struct cs35l41_dev_name" to "struct scodec_dev_name" for all other side codecs instead of the certain one.

Changes in v2:
- simplify the check of vendor id with Lenovo
- ThinkPad is one of Lenovo's brands, they suggested me to use ALC269_FIXUP_THINKPAD_ACPI.
- Add comments on ACARD_SINGLE_RANGE_EXT_TLV
- Add the range check for tas_priv->tasdevice[] in tas2781_acpi_get_i2c_res.
- remove acpi_subsystem_id
- Issue in Laptop 0x17aa38be ACPI talbe caused codec->bus->pci->subsystem_device is not equal to (codec->core.subsystem_id & 0xffff) in snd_hda_pick_fixup. The former is 0x3802 and the latter is 0x38be leads to getting the wrong fixup_id and enter into the wrong entry. Although, this issue has been raised to the laptop manufacturer, but the ACPI table is locked, cannot be changed any more. Correct the wrong entry in the code.
- Rename "struct cs35l41_dev_name" to "struct scodec_dev_name" for all other side codecs instead of one certain codec.
- Ignore the checkpatch complaints in alc269_fixup_tbl
- Drop the hunk which is irrelevant with my code in alc_fixup_headset_mode_alc255_no_hp_mic
- Add tiwai@suse.de into Cc list
- remove useless index
- combine ALC287_FIXUP_TAS2781_I2C_2 and ALC287_FIXUP_TAS2781_I2C_4 together as ALC287_FIXUP_TAS2781_I2C, The code view all the tas2781s in the laptop as one instance.
- delete the white space at the end of the line in alc_fixup_headset_mode_alc255_no_hp_mic
The patch looks almost fine. Just a few things:

The indentation in the patch doesn't look good. I don't want to be too strict about it, but this inconsistent indentation makes reading quite difficult, so better to be fixed. In general, it's recommended to align the opened parenthesis. (But, in the case above, you don't need to break the line at all.)

This should be rather applied differently. A similar workaround was found in the commit 56ec3e755bd1041d35bdec020a99b327697ee470 ALSA: hda/realtek: Apply fixup for Lenovo Yoga Duet 7 properly
