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
between the driver and the ACPI parser code.
Split out the relevant defines and enums into arm_arch_timer.h.
No functional change.

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.

This patchset:
(1)Preparation for adding GTDT support in arm_arch_timer:
1. Move some enums and marcos to header file;
2. Add a new enum for spi type;
3. Improve printk relevant code.
(2)Introduce ACPI GTDT parser: driver
From: Fu Wei <fu@linaro.org>
This patch add a new enum "spi_nr" and use it in the driver.
Just for code's readability, no functional change.
