tzc: Fix MISRA defects ...

The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
fixed.

The types tzc_region_attributes_t and tzc_action_t have been removed and
replaced by unsigned int because it is not allowed to do logical
operations on enums.

Also, fix some address definitions in arm_def.h.

Multi-console: Deprecate the `finish_console_register` macro ...

The `finish_console_register` macro is used by the multi console
framework to register the `console_t` driver callbacks. It relied
on weak references to the `ldr` instruction to populate 0 to the
callback in case the driver has not defined the appropriate
function. Use of `ldr` instruction to load absolute address to a
reference makes the binary position dependant. These instructions
should be replaced with adrp/adr instruction for position independant
executable(PIE). But adrp/adr instructions don't work well with weak
references as described in GNU ld bugzilla issue 22589.

This patch defines a new version of `finish_console_register` macro
which can spcify which driver callbacks are valid and deprecates the
old one. If any of the argument is not specified, then the macro
populates 0 for that callback. Hence the functionality of the previous
deprecated macro is preserved. The USE_FINISH_CONSOLE_REG_2 define
is used to select the new variant of the macro and will be removed
once the deprecated variant is removed.

All the upstream console drivers have been migrated to use the new
macro in this patch.

NOTE: Platforms be aware that the new variant of the
`finish_console_register` should be used and the old variant is
deprecated.

AArch64: Enable lower ELs to use pointer authentication ...

Pointer authentication is an Armv8.3 feature that introduces
instructions that can be used to authenticate and verify pointers.

Pointer authentication instructions are allowed to be accessed from all
ELs but only when EL3 explicitly allows for it; otherwise, their usage
will trap to EL3. Since EL3 doesn't have trap handling in place, this
patch unconditionally disables all related traps to EL3 to avoid
potential misconfiguration leading to an unhandled EL3 exception.

Fixes ARM-software/tf-issues#629

Whereas the GPT table is read with io_block, the binaries to be loaded
(e.g. BL33) cannot use it, as it is not suitable to read them block by

Introduce object pool allocator ...

The object pool allocator provides a simplistic interface to manage
allocation in a fixed-size static array. The caller creates a static
"object pool" out of such an array and may then call pool_alloc() to
get the next available object within the pool. There is also a variant
to get multiple consecutive objects: pool_alloc_n().

Note that this interface does not provide any way to free the objects
afterwards. This is by design and it is not a limitation. We do not
want to introduce complexity induced by memory freeing, such as
use-after-free bugs, memory fragmentation and so on.

plat/arm: Remove file arm_board_def.h ...

This file is shared between FVP and all CSS platforms. While it may be
true that some definitions can be common, it doesn't make sense
conceptually. For example, the stack size depends on the platform and so
does the SRAM size.

After removing them, there are not enough common definitions to justify
having this header, so the other definitions have been moved to the
platform_def.h of FVP, board_css_def.h and arm_def.h.

plat/arm: Move norflash driver to drivers/ folder ...

This way it can be reused by other platforms if needed.

Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.

Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.
