Input: xpad - fix Xbox One rumble stopping after 2.5 secs

Unlike previous Xbox pads, the Xbox One pad doesn't have "sticky" rumble
packets. The duration is encoded into the command and expiration is handled
by the pad firmware.

ff-memless needs pseudo-sticky behavior for rumble effects to behave
properly for long duration effects. We already specify the maximum rumble
on duration in the command packets, but it's still only good for about 2.5
seconds of rumble. This is easily reproducible running fftest's sine
vibration test.

It turns out there's a repeat count encoded in the rumble command. We can
abuse that to get the pseudo-sticky behavior needed for rumble to behave as
expected for effects with long duration.

By my math, this change should allow a single ff_effect to rumble for 10
minutes straight, which should be more than enough for most needs.

commit ef3714fdbc8d ("Input: bma150 - extend chip detection for bma180"),
adds bma180 chip-ids to the input bma150 driver, assuming that they are
100% compatible, but the bma180 is not compatible with the bma150 at all,
it has 14 bits resolution instead of 10, and it has quite different
control registers too.

Treating the bma180 as a bma150 wrt its data registers will just result
in throwing away the lowest 4 bits, which is not too bad. But the ctrl
registers are a different story. Things happen to just work but supporting
that certainly does not make treating the bma180 the same as the bma150
right.

Since some setups depend on the evdev interface the bma150 driver offers
on top of the bma180, we cannot simply remove the bma180 ids.

So this commit only removes the bma180 id when the bma180 iio driver,
