If an STM32MP15 board is compiled for SP_MIN, and a specific DT file
ending with "-sp_min.dts" exist, then this file will be used to generate
BL2 and BL32 DT.

This change centralises the logic that disables the default suffix rules
that Make provides. These rules are a hold-over from legacy standards of
Make, and occasionally conflict with our rules.

This elf file is used to build a binary file that concatenates BL2 and
its device tree blob. It then does not need PIE option, and this avoids
the following compilation error with some compiler versions:
error: PHDR segment not covered by LOAD segment

This commit streamlines directory creation by introducing a single
pattern rule to automatically make directories for which there is a
dependency.
We currently use several macros to generate rules to create directories
upon dependence, which is a significant amount of code and a lot of
redundancy. The rule introduced by this change represents a catch-all:
any rule dependency on a path ending in a forward slash is automatically
created.
Now, rules can rely on an unordered dependency (`|`) on `$$(@D)/` which,
when secondary expansion is enabled, expands to the directory of the
target being built, e.g.:
build/main.o: main.c | $$(@D)/ # automatically creates `build/`

This change introduces a few helper variables for dealing with verbose
and silent build modes: `silent`, `verbose`, `q` and `s`.
The `silent` and `verbose` variables are boolean values determining
whether the build system has been configured to run silently or
verbosely respectively (i.e. with `--silent` or `V=1`).
These two modes cannot be used together - if `silent` is truthy then
`verbose` is always falsy. As such:
make --silent V=1
... results in a silent build.
In addition to these boolean variables, we also introduce two new
variables - `s` and `q` - for use in rule recipes to conditionally
suppress the output of commands.
When building silently, `s` expands to a value which disables the
command that follows, and `q` expands to a value which supppresses
echoing of the command:
$(s)echo 'This command is neither echoed nor executed'
$(q)echo 'This command is executed but not echoed'
When building verbosely, `s` expands to a value which disables the
command that follows, and `q` expands to nothing:
$(s)echo 'This command is neither echoed nor executed'
$(q)echo 'This command is executed and echoed'
In all other cases, both `s` and `q` expand to a value which suppresses
echoing of the command that follows:
$(s)echo 'This command is executed but not echoed'
$(q)echo 'This command is executed but not echoed'
The `s` variable is predominantly useful for `echo` commands, where you
always want to suppress echoing of the command itself, whilst `q` is
more useful for all other commands.

The toolchain refactor change introduces the `${toolchain}-${tool}-id`
variables, which provide identifiers for all of the toolchain tools used
by the build system. This change replaces the various conditions that
are in use to identify these tools based on the path with a standard set
of comparisons against these new identifier variables.

This change migrates the values of `CC`, `CPP`, `AS` and other toolchain
variables to the new `$(toolchain)-$(tool)` variables, which were
introduced by the toolchain refactor patch. These variables should be
equivalent to the values that they're replacing.

LOADADDR variable is retrieved from line starting with RAM in map file.
But if the build path contains RAM, this keywords will appear several
times and the grep will fail. Correct that by really checking the line
starting with RAM thanks to grep '^RAM'.
