ARM64 / ACPI: Core functions for MADT parse
Implement core functions for GIC and GIC distributor entries
in MADT, after this patch, we can parse MADT for ARM now.
Here is the boot information for MADT parse:
ACPI: GIC (acpi_id[0x0000] gic_id[0x0000] enabled)
ACPI: GIC (acpi_id[0x0001] gic_id[0x0001] enabled)
ACPI: GIC (acpi_id[0x0002] gic_id[0x0002] enabled)
ACPI: GIC (acpi_id[0x0003] gic_id[0x0003] enabled)
ACPI: GIC (acpi_id[0x0004] gic_id[0x0004] disabled)
ACPI: GIC (acpi_id[0x0005] gic_id[0x0005] disabled)
ACPI: GIC (acpi_id[0x0006] gic_id[0x0006] disabled)
ACPI: GIC (acpi_id[0x0007] gic_id[0x0007] disabled)
ACPI: GIC Distributor (id[0x0000] address[0x2c001000] gsi_base[0])
Using ACPI (MADT) for SMP configuration information
NOTE: Parse GIC distributor for irq system is not implemented,
should fix it in the future.
