[PATCH] ACPI: Clarify resource conflict message

[Jean Delvare <jdelvare@suse.de>]

The message "ACPI: Device needs an ACPI driver" is misleading. The
device _may_ need an ACPI driver, if the BIOS implemented an API for
the device in question (which, AFAIK, can't be checked.) If not, then
either the generic "thermal" ACPI driver may be used, or nothing can
be done (other than a white list, if we really want to get hardware
monitoring on some machines.)

I propose to reword the message to:

ACPI: Device may still be supported by an ACPI driver

which I think is more correct. Comments and suggestions welcome.
