i2c/pca: Don't use *_interruptible
Unexpected signals can disturb the bus-handling and lock it up. Don't use interruptible in 'wait_event_*' and 'wake_*' as in commits dc1972d02747d2170fb1d78d114801f5ecb27506 (for cpm), 1ab082d7cbd0f34e39a5396cc6340c00bc5d66ef (for mpc), b7af349b175af45f9d87b3bf3f0a221e1831ed39 (for omap).
