[breaking-change] Fix polarity of "dm" signal in "memory" resource.

LB# and UB# enable writing their corresponding byte. The "m" in "dm"
means mask; that is, logical high masks (prevents) the byte from
being written. This means that it should use Pins(), not PinsN(),
to get the behavior implied by "mask".
