ddx/evergreen: Fix endian of ALU constants
The constants are written directly into a buffer object shared with the
card and we "forget" to swap them. This patch fixes it by doing the swap
in evergreen_set_alu_consts() in-place (ie, it modifies the buffer),
which should be fine with the way we use it in the ddx.
This makes everything work fine on my caicos card on a G5 including some
quik tests with Xv, gnome3 shell, etc...
Thanks a lot to Jerome Glisse for holding my hand through debugging that
(and finding the actual bug).
