Sanitise includes across codebase ...

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

rockchip: Move stdint header to the offending header file ...

The stdint header was introduced to rk3399's plat_sip_calls.c in order
to fix missing stdint definitions. However, ordering headers
alphabetically caused the fix to be ineffective, as stint was then
included after the offending header file (dfs.h).

Move the stdint include to that header to properly fix the issue.

Fix pointer type mismatch of handlers ...

Commit 4c0d03907652 ("Rework type usage in Trusted Firmware") changed
the type usage in struct declarations, but did not touch the definition
side.  Fix the type mismatch.

This includes the stdint header to declare the various types used within
the file, preventing build errors with recent GCC versions.

Fix order of remaining platform #includes ...

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

rockchip: implement hdcp key decryption feature for rk3399 ...

Decrypt device private keys which transfer from kernel, then stuff it to
DP controller. So that DP driver could start HDCP authentication in
kernel.

rk3399: dram: use PMU M0 to do ddr frequency scaling ...

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.

rockchip: rk3399: dram: remove dram_init and dts_timing_receive function ...

we can reuse the dram config from loader, so we can remove dram_init()
and dts_timing_receive() funciton in dram.c, add the dram_set_odt_pd()
function to get the odt and auto power down parameter from kernel.

This also removes the dcf_code_init function to allow the system to
actually boot.

rockchip: Break out common dram code for rk3399 ...

This renames dram.c and dram.h to dfs.c and dfs.h respectively. This
is to make room for common functionality between frequency scaling and
suspend code for the DRAM in a pair of common files named dram.c and
dram.h. It also removes a duplicate enum definition from
dram_spec_timing.h

rockchip: support plat SIP runtime service ...

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.
