net: stmmac: make variable data a u32

Browse Source 
Make data a u32 instead of an unsigned long, this way it is
explicitly the same width as the operations performed on it
and the same width as a writel store, and it cleans up sign
extention warnings when 64 bit static analysis is performed
on the code.
