MWDT supposes .device_states section as BSS because .device_states
variables defined as uninitialized. This causes the section marked
as NOLOAD section and OpenOCD does not take it in account while
flashing it into board memory.
Finally .device_states variables becomes initialized with garbage
from RAM.
In this PR it's suggested to clean .device_states in early init stage.
