lasips2: add named input gpio to handle incoming port IRQs

Browse Source 
The LASIPS2 device named input gpio is soon to be connected to the port output
IRQs. Add a new int_status field to LASIPS2State which is a bitmap representing
the port input IRQ status which will be enabled in the next patch.
