Previously WSTRB assumed all sent bytes were valdid, with these changes
only the first 4 bytes are valid (sent as 32 bit int). Might want
to revert these changes at some point.

Previoulsy WDATA repeated the data of bram_read_data across it's width.
Now, only the end of the channel contains bram_read_data's values.

Ticks 2 boxes on #1072 and tied to #1022

LGTM! For a future PR, I think we should break up that function because it is crazy big!
