Tegra210 PLLX uses the same sequences than then PLLC instances. So there
is no need to have a special registration function and ops struct for it.
Simplify the code by changing all references to the Tegra210 PLLX
registration function to the Tegra210 PLLC registration function and
avoid duplicate functionality.

Sparse reports the following warnings for structures and functions that
should be declared static:
drivers/clk/tegra/clk-tegra-super-gen4.c:70:35: warning: symbol
'tegra_super_gen_info_gen4' was not declared. Should it be static?
drivers/clk/tegra/clk-tegra-super-gen4.c:96:35: warning: symbol
'tegra_super_gen_info_gen5' was not declared. Should it be static?
drivers/clk/tegra/clk-tegra-super-gen4.c:174:13: warning: symbol
'tegra_super_clk_init' was not declared. Should it be static?
Fix this by making the above static.

Super clock divider control and clock source mux of Tegra210 has changed
a little against prior SoCs, this patch adds Gen5 logic to address those
differences.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into clk-next
clk: tegra: Changes for v4.3-rc1
This contains the DFLL driver needed to implement CPU frequency scaling
on Tegra.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are using
it. Also add in a clkdev.h include that was missing in a file
using clkdev APIs.

The DFLL clocksource was missing from the list of possible parents for
the fast CPU cluster. Add it to the list.

When pll_x is the parent of cclk_lp, PLLX_DIV2_BYPASS_LP determines
whether cclk_lp output is divided by 2. Set TEGRA_DIVIDER_2 so that
the clk_super driver is aware of this.
