Add the common extra.ld.S and customized rk3399.ld.S to extend
to more features for different platforms.
For example, we can add SRAM section and specific address to
load there if we need it, and the common bl31.ld.S not need to
be modified.
Therefore, we can remove the unused codes which copying explicitly
from the function pmusram_prepare(). It looks like more clear.

add dram driver, and kernel can through sip function talk to bl31 to
do ddr frequency scaling. and ddr auto powerdown.

This patch updates some things for rk3399, as following:
1) Add the new file to handle the pwm. (e.g. the pwm regulator)
Make sure that good deal with the pwm related things.
Also, remove some pwm setting for pmu.c.
2) Set the plls slow mode and bypass in suspend, and restore them.

This patch migrates the upstream platform makefiles to include the
console drivers from the new location in ARM Trusted Firmware code
base.

The `plat_psci_common.c` was moved to the new location `plat/common`
and a stub file was retained at previous location for compatibility. This
patch modifies the platform makefiles to include the file from the new
location.

Software executing in the normal world and in the trusted world at
exception levels lower than EL3 will request runtime services using the
SMC instruction.
See the documentation here:
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/
rt-svc-writers-guide.md
This to be implemented as an EL3 Runtime Service in rockchip BL31
platform port, using the "SiP Service Call" range as specified in the
SMC Calling Convention.
This doesn't support any SMC yet, we will support it in later.

We add plat parameter structs to support BL2 to pass variable-length,
variable-type parameters to BL31. The parameters are structured as a
link list. During bl31 setup time, we travse the list to process each
parameter. throuth this way, we can get the reset or power off gpio
parameter, and do hardware control in BL31. This structure also can
pass other parameter to BL31 in future.
There are 5 groups of GPIO (GPIO0~GPIO4), totally have 122 GPIOs
on rk3399 platform.
The pull direction(pullup or pulldown) for all of GPIOs are
software-programmable.
At the moment, we add the gpio basic driver since reset or power off
the devices from gpio configuration for BL31.
This patch modifies the upstream platform port makefiles to use the new
xlat_tables library files. This patch also makes mmap region setup common
between AArch64 and AArch32 for FVP platform port. The file `fvp_common.c`
is moved from the `plat/arm/board/fvp/aarch64` folder to the parent folder
as it is not specific to AArch64.

This patch adds to support the RK3368 and RK3399 SoCs.
RK3368/RK3399 is one of the Rockchip family SoCs, which is an
multi-cores ARM SoCs.
This patch adds support to boot the Trusted Firmware on RK3368/RK3399
SoCs, and adds support to boot secondary CPUs, enter/exit core
power states for all CPUs in the slow/fast clusters.
This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
* Support arm gicv2 & gicv3.
* Boot up multi-cores CPU.
* Add generic CPU helper functions.
* Support suspend/resume.
* Add system_off & system_reset implementation.
* Add delay timer platform implementation.
* Support the new porting interface for the PSCI implementation.
