Arm platforms: Fix DRAM address macros
On AArch32, ARM_DRAM1_BASE and ARM_DRAM1_SIZE constants are currently
32-bit values (because they are suffixed with UL and the value
0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When
summing them up, the result overflows the maximum value that can be
encoded in a 32-bit value so it wraps around and does not result in
the expected value.
This patch changes the suffix of these constants into ULL so that they
always are 64-bit values.

FVP: Enable PIE for RESET_TO_BL31=1
This patch enabled PIE for FVP when RESET_TO_BL31=1. The references
to BL31_BASE are replaced by BL31_START as being a symbol exported by
the linker, will create a dynamic relocation entry in .rela.dyn and
hence will be fixed up by dynamic linker at runtime. Also, we disable
RECLAIM_INIT_CODE when PIE is enabled as the init section overlay
creates some static relocations which cannot be handled by the
dynamic linker currently.

PIE: Position Independant Executable support for BL31
This patch introduces Position Independant Executable(PIE) support
in TF-A. As a initial prototype, only BL31 can support PIE. A trivial
dynamic linker is implemented which supports fixing up Global Offset
Table(GOT) and Dynamic relocations(.rela.dyn). The fixup_gdt_reloc()
helper function implements this linker and this needs to be called
early in the boot sequence prior to invoking C functions. The GOT is
placed in the RO section of BL31 binary for improved security and the
BL31 linker script is modified to export the appropriate symbols
required for the dynamic linker.
The C compiler always generates PC relative addresses to linker symbols
and hence referencing symbols exporting constants are a problem when
relocating the binary. Hence the reference to the
`__PERCPU_TIMESTAMP_SIZE__` symbol in PMF is removed and is now calculated
at runtime based on start and end addresses.

Make errata reporting mandatory for CPU files
Previously the errata reporting was optional for CPU operation
files and this was achieved by making use of weak reference to
resolve to 0 if the symbol is not defined. This is error prone
when adding new CPU operation files and weak references are
problematic when fixing up dynamic relocations. Hence this patch
removes the weak reference and makes it mandatory for the CPU
operation files to define the errata reporting function.

PIE: Use PC relative adrp/adr for symbol reference
This patch fixes up the AArch64 assembly code to use
adrp/adr instructions instead of ldr instruction for
reference to symbols. This allows these assembly
sequences to be Position Independant. Note that the
the reference to sizes have been replaced with
calculation of size at runtime. This is because size
is a constant value and does not depend on execution
address and using PC relative instructions for loading
them makes them relative to execution address. Also
we cannot use `ldr` instruction to load size as it
generates a dynamic relocation entry which must *not*
be fixed up and it is difficult for a dynamic loader
to differentiate which entries need to be skipped.

Add helper to return reference to a symbol
This patch adds a utility function to return
the address of a symbol. By default, the compiler
generates adr/adrp instruction pair to return
the reference and this utility is used to override
this compiler generated to code and use `ldr`
instruction.
This is needed for Position Independent Executable
when it needs to reference a symbol which is constant
and does not depend on the execute address of the
binary.
For example, on the FVP, the GICv3 register context is
stored in a secure carveout (arm_el3_tzc_dram) within
DDR and does not relocate with the BL image. Now if
BL31 is executing at a different address other than
the compiled address, using adrp/adr instructions to
reference this memory will not work as they generate an
address that is PC relative. The way to get around this
problem is to reference it as non-PC relative (i.e
non-relocatable location) via `ldr` instruction.

xlat: Fix compatibility between v1 and v2
There are several platforms using arm_setup_page_tables(), which is
supposed to be Arm platform only. This creates several dependency
problems between platforms.
This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib
v2 makefile. This way it is possible to detect from C code which version
is being used and include the correct header.
The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and
moved to a common folder. This way, when in doubt, this header can be
used to guarantee compatibility, as it includes the correct header based
on XLAT_TABLES_LIB_V2.
This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so
that is now locked in xlat lib v2) and ZynqMP (where it was added as a
workaround).
