Input: adp5589-keys - fix event count mask
The event mask was specified as 0xF (4 bits) when in reality is 0x1F (5 bits) in order to be capable of representing all FIFO length values from 0 to 16. This caused a problem: when the keypad reported 16 pending events the driver took it as 0, and did nothing. This in turn caused the keypad to re-issue the interrupt over and over again.
