IB/hfi1: make clear_all_interrupts static

clear_all_interrupts() in hw/hfi1/chip.c is currently global
but only used in the same file, so make it static.

There are also 'clear_all_interrupts' functions in i2c-nomadik and
emif.c but fortunately they're already static.

(Build and boot tested only, I don't have this hardware)
