Input: wm97xx - add possibility to control the GPIO_STATUS shift
This patch allows tweaking the behaviour of GPIO_STATUS register shift quirk that's in wm97xx-core. The problem with GPIO_STATUS register being shifted by one doesn't appear on all hardware it seems and causes problems with accelerated touchscreen drivers on Palm hardware. Therefore an accelerated touchscreen driver can select if the shift is/isn't happening on the hardware.
