SPM: Move S-EL1/S-EL0 xlat tables to TZC DRAM

A new platform define, `PLAT_SP_IMAGE_XLAT_SECTION_NAME`, has been
introduced to select the section where the translation tables used by
the S-EL1/S-EL0 are placed.

This define has been used to move the translation tables to DRAM secured
by TrustZone.

Most of the extra needed space in BL31 when SPM is enabled is due to the
large size of the translation tables. By moving them to this memory
region we can save 44 KiB.

A new argument has been added to REGISTER_XLAT_CONTEXT2() to specify the
region where the translation tables have to be placed by the linker.

fvp: Disable SYSTEM_SUSPEND when ARM_BL31_IN_DRAM

After returning from SYSTEM_SUSPEND state, BL31 reconfigures the
TrustZone Controller during the boot sequence. If BL31 is placed in
TZC-secured DRAM, it will try to change the permissions of the memory it
is being executed from, causing an exception.

The solution is to disable SYSTEM_SUSPEND when the Trusted Firmware has
been compiled with ``ARM_BL31_IN_DRAM=1``.

Hikey960: Change to use recommended power state id format

ARM Power State Coordination Interface (ARM DEN 0022D) chapter
6.5 "Recommended StateID Encoding" defines the state ID which can be
used by platforms. The recommended power states can be presented by
below values; and it divides into three fields, every field has 4 bits
to present power states corresponding to core level, cluster level and
system level.

0: Run
1: Standby
2: Retention
3: Powerdown

This commit changes to use upper recommended power states definition on
Hikey960; and changes the power state validate function to check the
power state passed from kernel side.

Enable SVE for Non-secure world

This patch adds a new build option, ENABLE_SVE_FOR_NS, which when set
to one EL3 will check to see if the Scalable Vector Extension (SVE) is
implemented when entering and exiting the Non-secure world.

If SVE is implemented, EL3 will do the following:

- Entry to Non-secure world: SIMD, FP and SVE functionality is enabled.

- Exit from Non-secure world: SIMD, FP and SVE functionality is
disabled. As SIMD and FP registers are part of the SVE Z-registers
then any use of SIMD / FP functionality would corrupt the SVE
registers.

The build option default is 1. The SVE functionality is only supported
on AArch64 and so the build option is set to zero when the target
archiecture is AArch32.

This build option is not compatible with the CTX_INCLUDE_FPREGS - an
assert will be raised on platforms where SVE is implemented and both
ENABLE_SVE_FOR_NS and CTX_INCLUDE_FPREGS are set to 1.

Also note this change prevents secure world use of FP&SIMD registers on
SVE-enabled platforms. Existing Secure-EL1 Payloads will not work on
such platforms unless ENABLE_SVE_FOR_NS is set to 0.

Additionally, on the first entry into the Non-secure world the SVE
functionality is enabled and the SVE Z-register length is set to the
maximum size allowed by the architecture. This includes the use case
where EL2 is implemented but not used.

ARM platforms: Fixup AArch32 builds

This patch fixes a couple of issues for AArch32 builds on ARM reference
platforms :

1. The arm_def.h previously defined the same BL32_BASE value for AArch64 and
AArch32 build. Since BL31 is not present in AArch32 mode, this meant that
the BL31 memory is empty when built for AArch32. Hence this patch allocates
BL32 to the memory region occupied by BL31 for AArch32 builds.

As a side-effect of this change, the ARM_TSP_RAM_LOCATION macro cannot
be used to control the load address of BL32 in AArch32 mode which was
never the intention of the macro anyway.

2. A static assert is added to sp_min linker script to check that the progbits
are within the bounds expected when overlaid with other images.

3. Fix specifying `SPD` when building Juno for AArch32 mode. Due to the quirks
involved when building Juno for AArch32 mode, the build option SPD needed to
specifed. This patch corrects this and also updates the documentation in the
user-guide.

4. Exclude BL31 from the build and FIP when building Juno for AArch32 mode. As
a result the previous assumption that BL31 must be always present is removed
and the certificates for BL31 is only generated if `NEED_BL31` is defined.

Replace magic numbers in linkerscripts by PAGE_SIZE

When defining different sections in linker scripts it is needed to align
them to multiples of the page size. In most linker scripts this is done
by aligning to the hardcoded value 4096 instead of PAGE_SIZE.

This may be confusing when taking a look at all the codebase, as 4096
is used in some parts that aren't meant to be a multiple of the page
size.
