mem: Encapsulate mapping gem5 to host address space
Create a function to encapsulate mapping an address in gem5's
address space to the host's address space. The returned value can
be used to access the contents of the given address.
As a side effect, make the local variable hostAddr use snake_case
to comply with gem5's coding style.
