fix(nxp-crypto): restricts generating nxp_mkvb via ns-world

Master-key-verification-blob (MKVB) value generated on request from
the secure world, is same to the MKVB value generated on request from
Normal world. Leading to the leak og MKVB to non-secure world.

Fix to prevent MKVB generation for requests originating from non-secure
world.
- For non-secure world, this SMC is return failure.

Additional fix for bound-check before continuing to generate the MKVB.

chore(docs): drop the "wfi" from `pwr_domain_pwr_down_wfi`

To allow for generic handling of a wakeup, this hook is no longer
expected to call wfi itself. Update the name everywhere to reflect this
expectation so that future platform implementers don't get misled.

fix(build): ensure `$(ROT_KEY)` depends on correct directory rules

In order for directories to be automatically created when used as a
dependency, they must end with a forward slash (`/`). This is because we
have a pattern rule (`%/`) to create a directory anywhere where a
directory is required as a direct dependency.

build: unify verbosity handling

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.
