maybe this is a gray area, but the rule here is to define following the
bit order, regardless of the meaning of the bit.
in gen8_de_port_aux_mask() I guess it's fine to leave it in the logical
order, but here it would be good not to create exceptions.
while at it, we could also add another commit to convert the surrounding
code to REG_BIT()
