hikey960: Fix race condition between hotplug and idles

From the hotplug testing on Hikey960, in some case cores fail to become
online in the system. When some cores are hotplugged off, if other
cores in the same cluster enter into CPU idle states at the meantime,
the cluster will be powered off. This introduces the state machine
malfunction in the power controller, thus when hotplug on the core
afterwards, it fails to boot up the core because the power controller
thinks the cluster is powered on.

This patch is to avoid race condition between hotplug and idles by
preventing cluster power off when some of cores in the cluster are
hotplugged off, if all cores in the same cluster are hotplugged off,
the cluster can be powered off.

Reduce memory needed for CoT description

When Trusted Board Boot is enabled, we need to specify the Chain of
Trust (CoT) of the BL1 and BL2 images. A CoT consists of an array
of image descriptors. The authentication module assumes that each
image descriptor in this array is indexed by its unique image
identifier. For example, the Trusted Boot Firmware Certificate has to
be at index [TRUSTED_BOOT_FW_CERT_ID].

Unique image identifiers may not necessarily be consecutive. Also,
a given BL image might not use all image descriptors. For example, BL1
does not need any of the descriptors related to BL31. As a result, the
CoT array might contain holes, which unnecessarily takes up space in
the BL binary.

Using pointers to auth_img_desc_t structs (rather than structs
themselves) means these unused elements only use 1 pointer worth of
space, rather than one struct worth of space. This patch also changes
the code which accesses this array to reflect the change to pointers.

Image descriptors not needed in BL1 or BL2 respectively are also
ifdef'd out in this patch. For example, verifying the BL31 image is
the responsibility of BL2 so BL1 does not need any of the data
structures describing BL31.

Current TF-A source fails to build with soft-float toolchain because assembler

SPM: Adjust size of virtual address space per partition

Rather than using a fixed virtual address space size, read all regions

address space size to the one the partition actually needs.

SPM: Refactor xlat context creation

Right now the virtual address space is fixed to
PLAT_VIRT_ADDR_SPACE_SIZE, so all base translation tables are the same
size and need the same alignment. The current code allocates the exact
space needed by this initial table.

However, a following patch is going to allow each partition to choose
the size of its address space based on the memory regions defined in
their resource description, so it isn't possible to determine this at
build time. As this optimization no longer applies, it has to be
removed.

Previously, the memory used by the exception vectors was reserved and
couldn't be used. Also, it always had to be mapped, forcing SPM to
generate translation tables that included the exception vectors as well
