malta: Use symbolic hardware addresses
The patch adds definitions of some hardware addresses and uses these
definitions.
It also replaces the type of all addresses from signed to unsigned values.
This is only a cosmetic change because addresses are unsigned values,
the functions called also expect unsigned values,
and we need no sign extension here.
