arm64, irqchip/gic-v3, ACPI: Move MADT GICC enabled check into a helper
ACPI, irqchip and the architecture code all inspect the MADT
enabled bit for a GICC entry in the MADT.
The addition of an 'online capable' bit means all these sites need
updating.
Move the current checks behind a helper to make future updates easier.
