[PATCH 2/2] Revert "Input: soc_button_array - debounce the buttons"

commit 5c4fa2a6da7fb ("Input: soc_button_array - debounce the buttons")
hardcoded all soc-button-array devices to use a 50ms debounce timeout
but this doesn't work on all hardware. The hardware I have on hand
actually prescribes in the ASL that the timeout should be 0:

GpioInt (Edge, ActiveBoth, Exclusive, PullUp, 0x0000,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,)
{ // Pin list
0x0000
}

Let the GPIO core program the debounce instead of hardcoding it into a
driver.

This reverts commit 5c4fa2a6da7fbc76290d1cb54a7e35633517a522.
