net: aquantia: Prepend hw access functions declarations with prefix 



Internal functions for registers and HW access were not prefixed.
This introduce noise in global kernel symbols. Here we add explicit prefix
'hw_atl' to all the HW access layer functions.
Alignment and styling were fixed as well.
