platform/x86: msi-wmi-platform: Fix typo in WMI GUID

Browse source

[ Upstream commit 97b726eb1d ]

The WMI driver core only supports GUID strings containing only
uppercase characters, however the GUID string used by the
msi-wmi-platform driver contains a single lowercase character.
This prevents the WMI driver core from matching said driver to
its WMI device.

Fix this by turning the lowercase character into a uppercase
character. Also update the WMI driver development guide to warn
about this.
