aarch64: Enable Statistical Profiling Extensions for lower ELs

SPE is only supported in non-secure state. Accesses to SPE specific
registers from SEL1 will trap to EL3. During a world switch, before
`TTBR` is modified the SPE profiling buffers are drained. This is to
avoid a potential invalid memory access in SEL1.

SPE is architecturally specified only for AArch64.

uniphier: embed ROTPK hash into BL1/BL2

Currently, ROTPK_NOT_DEPLOYED flag is set in plat_get_rotpk_info().
It is up to users how to retrieve ROTPK if the ROT verification is
desired. This is not nice.

This commit improves plat_get_rotpk_info() implementation and automates
the ROTPK deployment. UniPhier platform has no ROTPK storage, so it
should be embedded in BL1/BL2, like ARM_ROTPK_LOCATION=devel_rsa case.
This makes sense because UniPhier platform implements its internal ROM
i.e. BL1 is used as updatable pseudo ROM.

Things work like this:

- ROT_KEY (default: $(BUILD_PLAT)/rot_key.pem) is created if missing.
Users can override ROT_KEY from the command line if they want to
use a specific ROT key.

- ROTPK_HASH is generated based on ROT_KEY.

- ROTPK_HASH is included by uniphier_rotpk.S and compiled into BL1/BL2.

- ROT_KEY is input to cert_create tool.

Resolve build errors flagged by GCC 6.2

With GCC 6.2 compiler, more C undefined behaviour is being flagged as

This patch addresses issue caused by enums with values that exceed
maximum value for an int. For these cases the enum is converted to
a set of defines.

plat: Hikey960: fix the CPU hotplug

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.

CSS:Fix scpi "get_power_state" when ARM_PLAT_MT is set

The ARM_PLAT_MT bit enables the support for MT bit in
MPIDR format. This means that the level 0 affinity
represents the thread and CPU / Cluster levels are
at affinity level 1 and 2 respectively.
This was not catered for in the scpi 'css_scp_get_power_state, API.
Since the SCPI driver can only cater for single threaded CPUs,
this patch fixes the problem by catering for this shift by
effectively ignoring the Thread (level 0) affinity level.
