irqchip/mips-gic: Mark count and compare accessors notrace
gic_read_count(), gic_write_compare() and gic_write_cpu_compare() are often used in a sequence to update the compare register with a count value increased by a small offset. With small delta values used to update the compare register, the time to update function trace for these operations may be longer than the update timeout leading to update failure.
