platform/x86: intel_mid_powerbtn: Take a copy of ddata

Browse source

commit 5e0c94d3ae upstream.

The driver gets driver_data from memory that is marked as const (which
is probably put to read-only memory) and it then modifies it. This
likely causes some sort of fault to happen.

Fix this by taking a copy of the structure.
