To be able to see debug messages during boot, enable the debug settings
from Kconfig also for drivers in subdirectories.

Thanks, and this made me think. Can't we specify that these flags should
be inherited in subdirectories as well.

Going thru Kbuild doc again, looks like we can do this using subdir-ccflags-, so
the below patch can be simplified by doing

subdir-ccflags-$(CONFIG_DMADEVICES_DEBUG)  := -DDEBUG
subdir-ccflags-$(CONFIG_DMADEVICES_VDEBUG)  := -DVERBOSE_DEBUG

That way we don't need to add to subdirectories and future directory changes will
auto get these flags

Great find! I looked for such a solution but somehow missed it :( Will
update!
