LoongArch: Provisionally add ACPICA data structures

mainline inclusion
from mainline-v6.0-rc1
commit af6a1cfa
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5OHOB


CVE: NA

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

The LoongArch architecture is using ACPI, but the spec containing
the required updates still is in an unreleased state.

Instead of preventing the inclusion of the IRQ support into the
kernel, add the missing bits to the arch-specific parts of
the ACPICA support.

Once the ACPICA bits are updated to the version that supports
LoongArch, these bits can eventually be removed.
