platform/x86: x86-android-tablets: Add Lenovo Yoga Book X90F/L data

Browse Source 
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.
