mos6522: remove additional interrupt flag filter from mos6522_update_irq()
The datasheet indicates that the interrupt is generated by ANDing the
interrupt flags register (IFR) with the interrupt enable register (IER)
but currently there is an extra filter for the SR and timer interrupts.
Remove this extra filter to allow interrupts to be generated by external
inputs on bits 1 and 2 of ports A and B.
