platform/x86: x86-android-tablets: Add Vexia Edu Atla 10 tablet 5V data

The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.

Both are x86 ACPI tablets which ships with Android x86 as factory OS.
with a DSDT which 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().

Extend the existing support for the 9V version by adding support for
manually instantiating the I2C devices which are actually present on
the 5V version by adding the necessary device info to
the x86-android-tablets module.
