Clear the cpuidle flag when resuming from idle. This flag is set
when entering idle, and if it remains set when resuming, it can
prevent the cluster from powering off during the next system
suspend operation. During system suspend, all CPUs are plugged
out except the last CPU, which is suspended. If any of the
cpuidle flags are set at this point, the last CPU will be stuck
in a WFI loop and will not be powered off.
This problem only occurs during system suspend.

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.

The line
$(eval $(call FIP_ADD_IMG,SCP_BL2,--scp-fw))
is removed from
plat/hisilicon/hikey960/platform.mk
to clear the warning below:
Makefile:544: warning: overriding commands for target `check_SCP_BL2'
plat/hisilicon/hikey960/platform.mk:13: warning: ignoring old commands for
target `check_SCP_BL2'
$(eval $(call FIP_ADD_IMG,SCP_BL2,--scp-fw))
already exists in
Makefile
and applies to plat hikey960 so is redundant in
plat/hisilicon/hikey960/platform.mk

The patch fb7d32e588 migrated the CPU
libraries to have unique defines, prefixing them with the CPU name.
This patch migrates the hikey960 platform port to use the A53 specific
defines.

In CPU off callback function, the old code uses the function
hisi_test_pwrdn_allcores() to check if all CPUs in cluster have been
powered off and if it's valid then power off the whole cluster. But the
function hisi_test_pwrdn_allcores() only maintains the different power
states only for CPU suspend/resume flow, so it cannot return correct
states for CPU on/off flow.
This patch is to change use hisi_test_cpu_down() to check if all CPUs
have been powered off, so that can power off the whole cluster properly
when all CPUs in cluster have been hotplugged off.

Since the type of ADC value is always unsigned int, don't
need to check the value with negative value.

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.
