Move TSP to TZC secured DRAM

To allow BL31 to grow in SRAM, move TSP in TZC secured DRAM
by default.

Increase the BL31 max limit by one page.

Commit 6f625747

 ("Convert documentation to reStructuredText")
automatically converted all documents by a tool.  I see some parts
were converted in an ugly way (or, at least, it is not my intention).
Also, the footnote is apparently broken.

I checked this document by my eyes, and reformated it so that it looks
nicer both in plain text and reST form.

Add support to left-pad with zeroes in tf_printf

Disable PIE compilation option

io: block: fix block_read/write may read/write overlap buffer

SPM: Fix MM_COMMUNICATE_AARCH32/64 parameters

With this patch, ARM platforms are expected to define the macros
PLAT_ARM_SDEI_PRIVATE_EVENTS and PLAT_ARM_SDEI_SHARED_EVENTS as a list
of private and shared events, respectively. This allows for individual
platforms to define their own events.

This patch adds documentation that describes the design of the Secure
Partition Manager and the specific choices in their current
implementation.

The document "SPM User Guide" has been integrated into the design
document.

ARM TF does not work correctly if built with a version of gcc
that is configured to use PIE by default (e.g. Debian Stretch).

This patch identifies when such a version of gcc is being used
(by searching for --enable-default-pie) and adds -fno-PIE option
to TF_CFLAGS.

Makefile: Add ability to build dtb (v2)

The block operations were trying to optimize the number of memory
copies, and it tried to use directly the buffer supplied by the user
to them. This was a mistake because it created too many corner cases:

	1- It was possible to generate unaligned
	   operations to unaligned buffers. Drivers that were using
	   DMA transfer failed in that case.

	2- It was possible to generate read operations
	   with sizes that weren't a multiple of the block size. Some
	   low level drivers assumed that condition and they calculated
	   the number of blocks dividing the number of bytes by the
	   size of the block, without considering the remaining bytes.

	3- The block_* operations didn't control the
	   number of bytes actually copied to memory, because the
	   low level drivers were writing directly to the user buffer.

This patch rewrite block_read and block_write to use always the device
buffer, which the platform ensures that has the correct aligment and
the correct size.

This partially reverts commit d6b532b5

, keeping only the fixes to
the assertions. The changes related to the order of arguments passed
to the secure partition were not correct and violated the
specification of the SP_EVENT_COMPLETE SMC.

This patch also improves the MM_COMMUNICATE argument validation.  The
cookie argument, as it comes from normal world, can't be trusted and thus
needs to always be validated at run time rather than using an assertion.

Also validate the communication buffer address and return
INVALID_PARAMETER if it is zero, as per the MM specification.

Fix a few typos in comments and use the "secure partition" terminology
rather than "secure payload".

The security properties of some IP blocks are configured to secure mode
after reset. This means these IP blocks can only be accessed by cpus
in secure state by default. These should be configured correclty as needed.

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.
