Subject: [PATCH v16 01/15] 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, and
change "enum ppi_nr" to "enum arch_timer_ppi_nr" to avoid the potential
name clashes.
Also switch "enum ppi_nr" to "enum arch_timer_ppi_nr" in
arm_arch_timer.c.
No functional change.
