Subject: ACPI: Move PICM declaration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Variable PICM was not inside GNVS region and can use a static
initialisation value.

For most AMD platforms PICM default changes from 1 to 0.

Fix comments about PICM==0 used to indicate use of i8259 PIC for
interrupt delivery.
