[PATCH] PCI: rockchip: correct the use of FTS mask

[Brian Norris]

We're trying to mask out bits[23:8] while retaining [32:24, 7:0], but
we're doing the inverse. That doesn't have too much effect, since we're
setting all the [23:8] bits to 1, and the other bits are only relevant
for modes we're currently not using. But we should get this right.
