ACPI: Add a quirk for "AMILO PRO V2030" to ignore the timer overriding
commit f6b54f083cc66cf9b11d2120d8df3c2ad4e0836d upstream.
This is the 2nd part of fix for kernel bugzilla 40002:
"IRQ 0 assigned to VGA"
https://bugzilla.kernel.org/show_bug.cgi?id=40002
The root cause is the buggy FW, whose ACPI tables assign the GSI 16
to 2 irqs 0 and 16(VGA), and the VGA is the right owner of GSI 16.
So add a quirk to ignore the irq0 overriding GSI 16 for the
FUJITSU SIEMENS AMILO PRO V2030 platform will solve this issue.
