dtoc: Only generate the required files

At present all possible files are generated, even if some of them just
have a header and an empty body. It is better to generate only the files
that are needed, so that the two types of build (based on the setting of
OF_PLATDATA_INST) can be mutually exclusive.

This is intended to fix a strange problem sometimes found with CI:

   Building current source for 1 boards (1 thread, 40 jobs per thread)
      sandbox:  +   sandbox_spl
   +drivers/built-in.o: In function `dm_setup_inst':
   +drivers/core/root.c:135: undefined reference to
   `_u_boot_list_2_udevice_2_root'

   reference to `_u_boot_list_2_udevice_2_serial'
   ...

This likely happens when switching from !OF_PLATDATA_INST to
OF_PLATDATA_INST since running 'make xxx_defconfig" does not currently
cause any change in which files are generated. With !OF_PLATDATA_INST
the dt-device.c file has no declarations and this is assumed to be the
starting state. The error above seems to indicate that, after changing
to OF_PLATDATA_INST, the dt-uclass.c file is regenerated but the
dt-device.c files is not. This does not seem possible from the relevant
Makefile.spl rule:

   u-boot-spl-platdata := $(obj)/dts/dt-plat.o $(obj)/dts/dt-uclass.o
$(obj)/dts/dt-device.o

   cmd_dtoc = $(DTOC_ARGS) -c $(obj)/dts -C include/generated all

$(obj)/$(SPL_BIN).dtb
@[ -d $(obj)/dts ] || mkdir -p $(obj)/dts
$(call if_changed,dtoc)

It seems that this cannot regenerate dt-uclass.c without dt-device.c since
'dtoc all' is used. So here the trail ends for now.

In any case it seems better to generate files that are uses and not bother
with those that serve no purpose. So update dtoc to do this automatically.

In some rare cases different drivers are used for two phases. For example,
in TPL it may not be necessary to use the full PCI subsystem, so a simple
driver can be used instead.

This works in the build system simply by compiling in one driver or the
other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has
no way of knowing which code is compiled in for which phase, since it does
not inspect Makefiles or dependency graphs.

So to make this work for dtoc, we need to be able to explicitly mark
drivers with their phase. This is done by adding an empty macro to the
