reset cause is a generic functionality based on the soc
cru registers in rockchip. This can be used for printing
the cause of reset in cpuinfo or some other place where
reset cause is needed.
Other than cpuinfo, reset cause can also be using during
bootcount for checking the specific reset cause and glow
the led based on the reset cause.
So, let's separate the reset cause code from cpuinfo, and
add a check to build it for rk3399, rk3288 since these two
soc are supporting reset cause as of now.

reset reason can be used several stages of U-Boot bootloader
like SPL, U-Boot proper based on the requirements.
Clearing the status register end of get_reset_cause will end
up showing the wrong reset cause when it read the second time.
For example, if board resets, SPL reads the reset status as
RST whereas U-Boot proper reads the status as POR.
However, based on the latest testing clearing reset status
won't be required for determine the last reset cause or
following resets.

It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.

VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.
These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,
RK3288:
vopb_out: port {
#address-cells = <1>;
#size-cells = <0>;
vopb_out_edp: endpoint@0 {
reg = <0>;
remote-endpoint = <&edp_in_vopb>;
};
vopb_out_hdmi: endpoint@1 {
reg = <1>;
remote-endpoint = <&hdmi_in_vopb>;
};
vopb_out_lvds: endpoint@2 {
reg = <2>;
remote-endpoint = <&lvds_in_vopb>;
};
vopb_out_mipi: endpoint@3 {
reg = <3>;
remote-endpoint = <&mipi_in_vopb>;
};
};
RK3399:
vopb_out: port {
#address-cells = <1>;
#size-cells = <0>;
vopb_out_edp: endpoint@0 {
reg = <0>;
remote-endpoint = <&edp_in_vopb>;
};
vopb_out_mipi: endpoint@1 {
reg = <1>;
remote-endpoint = <&mipi_in_vopb>;
};
vopb_out_hdmi: endpoint@2 {
reg = <2>;
remote-endpoint = <&hdmi_in_vopb>;
};
vopb_out_mipi1: endpoint@3 {
reg = <3>;
remote-endpoint = <&mipi1_in_vopb>;
};
vopb_out_dp: endpoint@4 {
reg = <4>;
remote-endpoint = <&dp_in_vopb>;
};
};
here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.
The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.
Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.
Add the patch for fixing these vop modes for rk3399.

Few of the rockchip family SoC atleast rk3288,
rk3399 are sharing some cru register bits so
adding common code between these SoC families
would require to include both cru include files
that indeed resulting function declarations error.
So, create a common cru include as cru.h then
include the rk3399 arch cru include file and move
the common cru register bit definitions into it.
The rest of rockchip cru files will add it in future.
