dp8393x: Use long-word-aligned RRA pointers in 32-bit mode
Section 3.4.1 of the datasheet says,
The alignment of the RRA is confined to either word or long word
boundaries, depending upon the data width mode. In 16-bit mode,
the RRA must be aligned to a word boundary (A0 is always zero)
and in 32-bit mode, the RRA is aligned to a long word boundary
(A0 and A1 are always zero).
This constraint has been implemented for 16-bit mode; implement it
for 32-bit mode too.
