create dtb allocator

the parent commit (b106df2447d23d6b3fcffa7cc87edde218d054f3) discussed
the possibility of creating dtb device discovery. for that, we have
replaced wdt device discovery with dtb device discovery. in the future,
we will use the pci kernel module to use device discovery via a PCI
controller
