[PATCH 1/1] UBUNTU: SAUCE: wistron_btns: support Prestigio Wifi RF kill button over suspend

[TJ]

Bug: #346586

Other bugs: #53953 #53310

The Prestigio 157, an old no-name clone laptop uses input keys very similar to
the Wistron 1557/MS2141 with the addition of BIOS-controlled wireless radio
frequency kill switch.

This patch adds support for the RF kill switch control and adds manual identification
of the model.

The Prestigio does not expose any recognisable identity via dmidecode and so
requires manual selection at module init using force=1 keymap=prestigio
