timers: Simplify calc_index()
The level granularity round up of calc_index() does:
(x + (1 << n)) >> n
which is obviously equivalent to
(x >> n) + 1
but compilers can't figure that out despite the fact that the input range
is known to not cause an overflow. It's neither intuitive to read.
Just write out the obvious.
