platform/x86: x86-android-tablets: Move Acer info to its own file 

Acer has several x86 based Android tablets which need x86-android-tablets
support to work around their broken ACPI tables.

At the moment x86-android-tablets only support one model, move this to
its own file before adding support for more models to avoid needing to
move more code around later.
