clocksource: sh_tmu: Make undefined TCOR behaviour less undefined.

Browse source 
Avoid undocumented vague TMU behavior when zero value is set to TCOR.

This primarily fixes up issues encountered under qemu with a zero-length
period, while the hardware itself is fairly ambivalent one way or the
other.
