    ACPI: x86: Add skip i2c clients quirk for Nextbook Ares 8A
    
    [ 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.
