Make lpc_interrupt() attribute const

It's a placeholder at the moment, which makes it easy to say "this never
gives a different answer". It also silences our one compiler warning:

hw/lpc.c: In function 'lpc_interrupt':
hw/lpc.c:457:6: warning: function might be candidate for attribute 'const' [-Wsuggest-attribute=const]
