Allwinner H3 features a thermal sensor like the one in A33, but has its
register re-arranged, the clock divider moved to CCU (originally the
clock divider is in ADC) and added a pair of bus clock and reset.
Update the binding document to cover H3.

I guess mod instead of ths would be more consistent.
In fact I will prefer "sample" here if not "ths", as it's used
for the sampling, not like other mod clocks, which controls
all the IP block's logic.
