_calc_dynamic_ram_rate is defined inside an #ifdef but called
later in the same file outside of that #ifdef, which can cause a
build error:
drivers/clk/tegra/clk-pll.c: In function '_tegra_clk_register_pll':
drivers/clk/tegra/clk-pll.c:1541:29: error: '_calc_dynamic_ramp_rate'
undeclared (first use in this function)
This moves both _calc_dynamic_ram_rate and _pll_fixed_mdiv in
front of the #ifdef to make all configurations compile again.

Fixes: 44c8b9fa432c ("clk: tegra: pll: Fix _pll_ramp_calc_pll logic and
_calc_dynamic_ramp_rate")
----
The patch that caused it appears to be older, but I only ran into
the randconfig bug today for the first time. Apparently the commit
is only in linux-next at the moment, not in 4.4-rc1
