Subject: [PATCH v8 1/9] clocksource/drivers/arm_arch_timer: Move enums and defines to header file

From: Fu Wei <fu.wei@...aro.org>

To support the arm_arch_timer via ACPI we need to share defines and enums
between the driver and the ACPI parser code.

Split out the relevant defines and enums into arm_arch_timer.h.
No functional change.
