[v2,0/4] clk: shrink struct clk_fractional_divider

Message

This serie removes 2 fields from struct clk_fractional_divider and shrinks it
from 72 to 56 bytes.

Instead of been pre-computed, thse fields are now computed when needed.

The first patch makes the [mn]mask fields useless.
Patch 2 and 3 make some needed modification in 2 drivers that where using these
fields.
Finally, patch 4 removes the now used fields.

This is a another approach of what was proposed in v1. (i.e. just moving a field
to shrink from 72 ro 64 bytes)

Compared to v1, all 4 patches are new.
