Input: adp5588-keys - do not explicitly set device as wakeup source

I2C core will set up device as a wakeup source and will configure interrupt
as a wakeup interrupt if client is created with I2C_CLIENT_WAKE flag. Let's
rely on this facility and to not unconditionally set up the device as
wakeup device in the driver.
