ACPICA: MADT: Add loong_arch-specific APICs support

Browse Source 
ACPICA commit 1dc530059a3e6202e941e6a9478cf30f092bfb47

loong_arch-specific interrupt controllers (similar to APIC) are added
in the next revision of ACPI Specification (current revision is 6.4),
which including CORE_PIC (CPUINTC), LIO_PIC (LIOINTC), EIO_PIC (EIOINTC),
HT_PIC (HTVECINTC), BIO_PIC (PCHINTC), LPC_PIC (PCHLPC) and MSI_PIC
(PCHMSI). This patch add their definition.

ACPI changes of loong_arch-specific interrupt controllers have already
been approved in the ECRs, and will be public in the next revision of
ACPI Specification.
