JR0 and JR1 of CAAM are owned by SECO, only kick the power
of JR2 and JR3 here and assign the resources to be accessed
by secure world.

This patch adds support for cpuidle with CPU powerdown,
there will be 3 idle states in Linux kernel:
1: wfi;
2: cpu power down;
3: cluster power down.
As Linux kernel needs a broadcast timer for waking up
CPU when whole CLUSTER is powerdown, GPT is adopted as
broadcast timer, and to make the clock & power management
easy for Linux kernel to avoid many workaround/hake in
Linux kernel, TF-A will handle GPT's power & clock management
as well as registers save/restore when suspend/resume.
Also, psci power states are used to determine CORE/CLUSTER/SYSTEM
power state to distinguish CPU idle and SYSTEM suspend which share
same domain_suspend callback.
The SoC IPs register mmap regions are merged into 1 large
section to cover all the SoC IPs register ranges TF-A needs,
this is to save mmap regions and make it simple.

The irqstr for scu2 is used for AP wakeup if gic is power off,
so this resource need to be added to the sec rsrc.

Change to search the ATF owned memory regions and assign them to non-secure
OS partition. Not allocate new memory region for each one.

Not only the resources, but also the memory regions need to assign to
non-secure partition. Otherwise, when the boot partition is secured,
the OS non-secure partition can't access any memory.
This patch currently assign all memory to NS partition, since it is not
isolated, the current secure partition also can access them. In future,
may need to change the regions for reserving some memory in secure
partition for ATF and BL32.

Add necessary resources to secure partition for protection.
Also add in functionality to allow for register access
of some secure-owned peripherals.
These peripherals will still be protected from power or
clk changes.
