ACPI: x86: Add skip i2c clients quirk for Medion Lifetab S10346
The Medion Lifetab S10346 is a x86 tablet which ships with Android x86 as factory OS. The Android x86 kernel fork ignores I2C devices described in the DSDT, except for the PMIC and Audio codecs. As usual the Medion Lifetab S10346's DSDT contains a bunch of extra I2C devices which are not actually there, causing various resource conflicts. Add an ACPI_QUIRK_SKIP_I2C_CLIENTS quirk for the Medion Lifetab S10346 to the acpi_quirk_skip_dmi_ids table to woraround this.
