ARM: shmobile: lager: set .debounce_interval
In R-Car GPIO hardware block, 'chattering removal' feature can be
enabled on GPIO-n-[3:0] pins, but it's not supported on rest of pins
GPIO-n-[31:4].
Set an appropriate debounce interval, instead. We could confirm that
spurious/unnecessary GPIO interrupts are prevented by this settings.
