[ Upstream commit 69d6b37695c1f2320cfa330e1e1636d50dd5040a ]
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 (the Android x86 kernel fork ignores I2C devices described in the DSDT).
On this specific model this just not cause resource conflicts, one of the probe() calls for the non existing i2c_clients actually ends up toggling a GPIO or executing a _PS3 after a failed probe which turns the tablet off.
Add a ACPI_QUIRK_SKIP_I2C_CLIENTS for the Nextbook Ares 8 to the acpi_quirk_skip_dmi_ids table to avoid the bogus i2c_clients and to fix the tablet turning off during boot because of this.
Also add the "10EC5651" HID for the RealTek ALC5651 codec used in this tablet to the list of HIDs for which not to skipi2c_client instantiation, since the Intel SST sound driver relies on the codec being instantiated through ACPI.
