irqchip/loongson-htvec: Add ACPI init support

Browse Source 
HTVECINTC stands for "HyperTransport Interrupts" that described in
Section 14.3 of "Loongson 3A5000 Processor Reference Manual". For more
information please refer Documentation/loongarch/irq-chip-model.rst.

Though the extended model is the recommended one, there are still some
legacy model machines. So we add ACPI init support for HTVECINTC.
