Makefile.mk: Include build/dsdt.d at the same time as DEPENDENCIES
Instead of including the generated dependency file during the evaluation
of asl_template, add it to the DEPENDENCIES variable so that it is
included at the same time as the rest of the .d files in the top level
Makefile. This makes the handling of .d files cleaner as all of them are
processed in the same way. Tracking all of them in a single variable
also prevents any from being missed if any post-processing is performed
on them, such as running them through the fixdep utility from the Linux
kernel project to replace the config.h dependency with only the configs
that are used.
This should be safe since asl_template is evaluated while calling
includemakefiles, which is occurs before the files in DEPENDENCIES are
included.
TEST:
1. Build dell/e6400
2. Run `touch src/mainboard/dell/e6400/dsdt.asl` (defined as a
prerequisite of build/dsdt.aml in build/dsdt.d)
3. Run `make --debug=b`
4. Verify that dsdt.aml was rebuilt due dsdt.asl being newer than target
