Cyberbook T116
The Cyberbook T116 rugged tablet comes in both Windows and Android versions
and even on the Android version the DSDT is mostly sane. This tablet has
2 extra general purpose buttons in the row with the power + volume-buttons,
labeled P and F.
Use the x86-android-tablets infra to create a gpio-button device for these
2 extra buttons.

The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86
as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there, causing various resource conflicts. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the I2C devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.
Note the Ares 8A is the Cherry Trail (CHT) model, the regular Ares 8
is Bay Trail (BYT) based and was already supported. This also updates
the comments for the BYT model to point out this is the BYT model.

The Lenovo Yoga Book X90F/L is a x86 ACPI tablet which ships with Android
x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there, causing various resource conflicts. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the I2C + other devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.

models only
When support for instantiating an i2c-client for the fuel-gauge was
added for the Windows based Yoga Book YB1-X91F/L models, the assumption
was made that this would apply to the Android based YB1-X90F/L models too.
But these have a completely different BIOS with completely different DMI
strings. Update the existing YB1-X91 support to reflect that it only
applies to the YB1-X91F/L models.

C1010
The Peaq C1010 tablet has a special "Dolby" button. This button has
a WMI interface, but this is broken in several ways:
1. It only supports polling
2. The value read on polling goes from 0 -> 1 for one poll on both edges
of the button, with no way to tell which edge causes the poll to
return 1.
3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID).
There currently is a WMI driver for this, but it uses several kludges
to work around these issues and is not entirely reliable due to 2.
Replace the unreliable WMI driver by using the x86-android-tablets code
to instantiate a gpio_keys device for this.

In order to have a single MODULE_DEVICE_TABLE(dmi, ...), while allowing
splitting the board descriptions into multiple files, add a new separate
file for the DMI match table.
