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
