Global GPIO interrupt handler

[atwardzik]

Task description

Currently pin interrupt is assigned directly to the WIZnet W5100s INT pin. As there is only one IO_IRQ_BANK0 in NVIC, there must be a single function for receiving the interrupt and based on the pin of interrupt it should determine to which interrupt subroutine it should jump.

Goal

Single IO_IRQ_BANK0 handler determining pins on which the interrupt was requested and jumping to specific handler
