Merge branch 'acpi-init'
* acpi-init:
clocksource: cosmetic: Drop OF 'dependency' from symbols
clocksource / arm_arch_timer: Convert to ACPI probing
clocksource: Add new CLKSRC_{PROBE,ACPI} config symbols
clocksource / ACPI: Add probing infrastructure for ACPI-based clocksources
irqchip / GIC: Convert the GIC driver to ACPI probing
irqchip / ACPI: Add probing infrastructure for ACPI-based irqchips
ACPI: Add early device probing infrastructure
