platform/x86: x86-android-tablets: Add lid-switch gpio-keys pdev to Asus ME176C + TF103C

Browse Source 
The Asus ME176C + TF103C both have a lid-switch (for a cover in the ME176C
case), add a gpio-keys platform-device and platform-data describing the
lid-switch on both.

Note the "intel-int3496" in the asus_me176c_tf103c_pdevs[] array is not
new / not a change. This was already present in the generic int3496_pdevs[]
array, to which pdev_info pointed before. The int3496_pdevs[] array
contains just this entry for boards which only need that single pdev.
