"hw/mips/cpudevs.h" contains declarations which are specific
to the MIPS architecture; it doesn't make sense for these to
be called from a non-MIPS architecture. Move the declarations
to "target/mips/cpu.h".

Previous implementation of MIPS cp0_timer computes a
cp0_count_ns based on input clock. However rounding
error of cp0_count_ns can affect precision of cp0_timer.
Using clock API and a divider for cp0_timer, so we can
use clock_ns_to_ticks/clock_ns_to_ticks to avoid rounding
issue.
Also workaround the situation that in such handler flow:
count = read_c0_count()
write_c0_compare(count)
If timer had not progressed when compare was written, the
interrupt would trigger again.
