Subject: [PATCH 0/2] clk: add helpers for generic clocks

This series exports an helper providing the divider mask in the generic
divider and helpers to translate the between the index and the register
value in the generic mux.

The goal is to avoid duplicating this code in clock providers deriving
from these generic clocks, something I plan do doing in upcoming
changeset for meson clocks [0]

In patch 1, I have 's/div_mask/clk_div_mask' to avoid the conflict with
tegra's divider, which also defines the macro div_mask() but does not
actually derives from the generic divider.
