[PATCH 14/23] kernel: generic counter for interrupt errors

We currently have counters for spurious interrupt spread over all the individual architectures. Mostly done in the arch's ack_bad_irq(), sometimes also in arch specific drivers. It's time to consolidate this code duplication: * introduce a global counter and inlined accessors * increase the c
