(1)Preparation for adding GTDT support in arm_arch_timer:
1. Move some enums and marcos to header file;

From: Fu Wei
This patch adds support for parsing arch timer in GTDT,
provides some kernel APIs to parse all the PPIs and
always-on info in GTDT and export them.
By this driver, we can simplify arm_arch_timer drivers, and
separate the ACPI GTDT knowledge from it.

To support the arm_arch_timer via ACPI we need to share defines and enums

Any suggestion ?
If we make the first stage timeout is timeout/2, this violates the
definition of timeout.
I don't think users expect interrupt, panic or reboot at timeout/2.
And WS1 definitely isn't a backup of WS0.

The patch update arm_arch_timer driver to use the function
provided by the new GTDT driver of ACPI.
By this way, arm_arch_timer.c can be simplified, and separate
all the ACPI GTDT knowledge from this timer driver.
