dmtimer(4), macppc, powerpc64, riscv64: init stathz, profhz like other platforms

[Scott Cheloha]

Almost every platform initializes stathz and profhz like this:

        stathz = hz;
        profhz = stathz * 10;

This patch brings a few stragglers in line with everyone else.

This does not change stathz and profhz on the listed platforms: hz is
100 in every case.

ok?
