Currently, enable_mmu_el1() or enable_mmu_el3() is kept outside the
common function because the appropriate one must be chosen.

Use enable_mmu() and move it to the common function.

The I/O register region will be changed in the next SoC. Make it
configurable.

The next SoC supports the same UART, but the register base will be
changed. Make it configurable.

BL2_BASE, BL31_BASE, and BL32_BASE are defined in platform_def.h,
that is, determined at link-time.

On the other hand, BL2_END, BL31_END, and BL32_END are derived from
the symbols produced by the linker scripts. So, they are fixed-up
at run-time if ENABLE_PIE is enabled.

To make it work in a position-indepenent manner, use BL_CODE_BASE and
BL_END, both of which are relocatable.

Many parts of the code were duplicating symbols that are defined in
include/common/bl_common.h. It is better to only use the definitions in
this header.

As all the symbols refer to virtual addresses, they have to be
uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.
