media: atomisp: reduce debug printk rate when IRQs are received
Currently, when an EOF IRQ is received, it generates two messages:
[ 59.191893] atomisp-isp2 0000:00:03.0: irq:0x200000
[ 59.191913] atomisp-isp2 0000:00:03.0: atomisp_isr EOF exp_id 142, asd 0
Flooding the dmesg with lots of messages per second. The same
pattern happens for all other IRQs.
Change the logic for printing just one message per IRQ and
rate-limit those, as, for debugging purposes, it is usually
interesting to know that IRQs are being received, but not
displaying every single one.
