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.

This patch makes all the defines in the CPU libraries unique,
by prefixing them with the CPU name.
NOTE: PLATFORMS USING THESE MACROS WILL HAVE TO UPDATE THEIR CODE
TO START USING THE UPDATED NAMES

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

BL2 loads MCU firmware & BL31 on hikey960 platform. The MCU firmware
is used to implement low power feature.

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.

The cluster 0 doesn't rely on PSCI to enable it; so enable CCI port
for cluster 0 in BL31 platform setup flow.

Fix for CPU topology so present the CPU core numbers for two clusters;
Base on this fixing, the PSCI can maintain correct power states.

BL2 is used to load BL31 and SCP_BL2. In HiKey platform, SCP_BL2
is the mcu firmware that is used to scale cpu frequency and switch
low power mode.

Initialize regulators, pins and eMMC in BL1. Only SRAM could be used in BL1.
So BL2 will be loaded from eMMC into SRAM later.
