This change forces LD to sort all input sections by alignment when
allocating them within an output section. This is done in some places
explicitly in the linker scripts today, but this makes sure we don't
miss any easy targets.

The following build system variables have been renamed:
- `LINKERFILE` -> `DEFAULT_LINKER_SCRIPT`
- `BL_LINKERFILE` -> `DEFAULT_LINKER_SCRIPT_SOURCE`
- `<IMAGE>_LINKERFILE` -> `<IMAGE>_DEFAULT_LINKER_SCRIPT_SOURCE`
These new names better reflect how each variable is used:
1. the default linker script is passed via `-dT` instead of `-T`
2. linker script source files are first preprocessed
Additionally, linker scripts are now placed in the build directory
relative to where they exist in the source directory. For example,
the `bl32/sp_min/sp_min.ld.S` would now preprocess to
`sp_min/sp_min.ld` instead of just `bl32.ld`
BREAKING-CHANGE: The `LINKERFILE`, `BL_LINKERFILE` and
`<IMAGE_LINKERFILE>` build system variables have been renamed. See the
commit message for more information.

To make software license auditing simpler, use SPDX[0] license
identifiers instead of duplicating the license text in every file.

These source file definitions should be defined in generic
Makefiles so that all platforms can benefit. Ensure that the
symbols are properly marked as weak so they can be overridden
by platforms.
NOTE: This change is a potential compatibility break for
non-upstream platforms.

The Firmware Update (FWU) feature needs support for an optional
secure world image, BL2U, to allow additional secure world
initialization required by FWU, for example DDR initialization.
This patch adds generic framework support to create BL2U.
NOTE: A platform makefile must supply additional `BL2U_SOURCES`
to build the bl2u target. A subsequent patch adds bl2u
support for ARM platforms.
