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.

This patch defines pr_fmt(fmt) for all pr_* functions,
then the pr_* doesn't need to add "arch_timer:" everytime.
Also delete some Blank Spaces in arch_timer_banner,

The patch update arm_arch_timer driver to use the function

ly,
because this GTDT patchset can work without it, this readq support is
a optimizing.
I also can see another arm-related driver are using readq in this way(
#ifdef readq): bus/arm-ccn.c
And some other drivers are also doing this.

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 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
