Armin Wolf c7891884a5 platform/x86: dell-ddv: Warn if ePPID has a suspicious length
On some systems (like the Dell Inspiron 3505), the acpi operation
region holding the ePPID string is two bytes too short, causing
acpi functions like ToString() to omit the last two bytes.
This does not happen on Windows, supposedly due to their implementation
of ToString() ignoring buffer boundaries.
Inform users if the ePPID length differs from the Dell specification
so they can complain to Dell to fix their BIOS.

Tested on a Dell Inspiron 3505.
