MISRA C-2012 Rule 7.3 violation: lowercase l shall not be used as literal suffixes.
This patch resolves this for the ULL() macro by using ULL suffix instead
of the ull suffix.

This reverts commit fdae60b6ba.
The commit fdae60b6ba changed the
parameter encoding for the hikey960. However that implies a DT change
in the kernel side. After submitting the DT change for upstreaming,
the backward compatibility issue and the interface change raise some
concerns from the Linux community about the issues related to kernel <->
ATF alignment. There is no way to detect a mis-alignment of those
without a deep knowledge of the ATF and the kernel. Furthermore, the
failing calls to PSCI in the idle path (because of bad parameters), will
lead to busy looping, implying: thermal issues and extra energy
consumption.
In regard of the Linux community concerns, the potential issues when the
ATF and the kernel are not aligned, it is preferable to revert the
commit.

ARM Power State Coordination Interface (ARM DEN 0022D) chapter
6.5 "Recommended StateID Encoding" defines the state ID which can be
used by platforms. The recommended power states can be presented by
below values; and it divides into three fields, every field has 4 bits
to present power states corresponding to core level, cluster level and
system level.
0: Run
1: Standby
2: Retention
3: Powerdown
This commit changes to use upper recommended power states definition on
Hikey960; and changes the power state validate function to check the
power state passed from kernel side.

These macros are only defined for corresponding image,
and they are undefined for other images. It means that we have
to use ifdef or defined() instead of relying on being 0 by default.

Otherwise, BL2 tries to load a BL32 image and triggers
assert(result == 0)
in
plat_get_image_source()
in hikey{960}_io_storage.c
in a debug build, or displays
ERROR: BL2: Failed to load image
in a release build.

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.

Support BL1 on HiKey960 platform. When recovery mode is detected,
BL1 loads NS BL1U that flushs images into UFS. When normal boot
mode is detected, BL1 loads BL2.
