[PULL 04/22] pmu: fix duplicate autopoll mask variable

[Mark Cave-Ayland]

It seems that during the initial work to introduce the via-pmu ADB support a
duplicate autopoll mask variable was accidentally left in place.

Remove the duplicate autopoll_mask variable and switch everything over to
use adb_poll_mask instead.
