Remove struct rockchip_pm_ops_cb and instead of using weak functions
implement; in this way we want the codes look clear and simple;

We used dcf do ddr frequency scaling, but we just include a dcf
binary, it hard to maintain later, we have M0 compile flow in ATF,
and M0 can also work for ddr frequency scaling, so let's use it.

We are duplicating this macro define, and it is useful enough
to be placed in the common place.

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.

For save power cosumption, if gpio power supply shut down, we need to
set gpio2 ~ gpio4 to input and HiZ status when suspend, and recovery
they status when rusume. we do it base on apio pass from loader.

some specific board need to disable/enable specific gpio when
suspend/resume, so we add this function, bootloader can pass the
specific gpio, and we can handle these gpios in bl31 suspend/resuem
function.

For the PMU design, we don't expect to get the interrupts before enter
the power mode. Since that will cause the confusion for the state
machine in the power mode.

1.Fixes the suspend/resume some bugs.
2.Add the power domain for saving power consumption.
3.Add cpu clusters suspend for rk3399 SoCs

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 adds to support the suspend/resume for rk3399 SoCs.

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.
