Currently, the counter frequency detection call(arch_timer_detect_rate)
combines all the ways to get counter frequency: device-tree property,
system coprocessor register, MMIO timer. But in the most of use cases,
we don't need all the ways to try:
For example, reading device-tree
From: Fu Wei
Because arch_timer_needs_of_probing is only for booting with device-tree,
but arch_timer_common_init is a generic init call which shouldn't include
the FW-specific code. It's better to put arch_timer_needs_of_probing into
DT init function.
But for per-cpu timer
From: Fu Wei
When system init with device-tree, we don't know which node will be
initialized first. And the code in arch_timer_common_init should wait
until per-cpu timer and MMIO timer are both initialized. So we need
arch_timer_needs_probing to detect the init status of system.
But currently
From: Fu Wei
The patch refactor original memory-mapped timer init code:
(1) Refactor "arch_timer_mem_init", make it become a common code for
memory-mapped timer init.
(2) Add a new function "arch_timer_mem_of_init" for DT init.

Thanks for your testing,
So I will apply your Tested-by in 1~8, 11, 12, 15 in my next patchset.

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.
