target/mips: Don't use clock_get_ns() in clock period calculation
Currently the MIPS code uses the old clock_get_ns() API to
calculate a time length in nanoseconds:
cpu->cp0_count_rate * clock_get_ns(MIPS_CPU(cpu)->clock)
This relies on the clock having a period which is an exact number
of nanoseconds.
Switch to the new clock_ticks_to_ns() function, which does the
multiplication internally at a higher precision.
