Note that the arguments passed during the SMC call don't comply with the
SPCI specifications. This will be fixed in following patches, but it is
needed to implement a few more SPCI SMCs to be able to do it. The
current code allows us to start testing it.

SPM needs to map a number of regions on behalf of the secure partition.
Previously, it used to get a list of them from platform code using the
plat_get_secure_partition_mmap() API. Now it gets them from the resource
description structure.

The SPM<->SP shared buffer is mapped dynamically at EL3. This buffer is
used to pass information between SPM and SP, so it must be mapped at EL3
as well in order to be used by SPM.

Dynamic translation tables have been enabled when the Trusted Firmware
is compiled with SPM support.

Instead of having a different initialization routine than the rest of
the codebase, use the common implementation.

The function xlat_arch_is_granule_size_supported() can be used to check
if a specific granule size is supported. In Armv8, AArch32 only supports
4 KiB pages. AArch64 supports 4 KiB, 16 KiB or 64 KiB depending on the
implementation, which is detected at runtime.

The function xlat_arch_get_max_supported_granule_size() returns the max
granule size supported by the implementation.

Even though right now they are only used by SPM, they may be useful in
other places in the future. This patch moves the code currently in SPM
to the xlat tables lib so that it can be reused.

In the context management library, cm_setup_context() takes the
information in ep_info to fill the registers x0-x7. This patch replaces
the current code that sets them manually by the correct initialization
code.

The current internal names are too long, which makes it hard to write
code as many lines overflow the limit and need to be split, which may
not help the reader.

Move all information related to a Secure Partition to the struct
secure_partition_context_t.

This requires an in-depth refactor because most of the previous code of
SPM relied on global information.
