ACPI: Fix Generic Initiator Affinity _OSC bit 

mainline inclusion
from mainline-v6.10-rc1
commit d0d4f1474e36b195eaad477373127ae621334c01
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB8X0F

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d0d4f1474e36b195eaad477373127ae621334c01



--------------------------------

The ACPI spec says bit 17 should be used to indicate support
for Generic Initiator Affinity Structure in SRAT, but we currently
set bit 13 ("Interrupt ResourceSource support").

Fix this by actually setting bit 17 when evaluating _OSC.
