clk: add clk accuracy retrieval support
The clock accuracy is expressed in ppb (parts per billion) and represents
the possible clock drift.
Say you have a clock (e.g. an oscillator) which provides a fixed clock of
20MHz with an accuracy of +- 20Hz. This accuracy expressed in ppb is
20Hz/20MHz = 1000 ppb (or 1 ppm).
Clock users may need the clock accuracy information in order to choose
the best clock (the one with the best accuracy) across several available
clocks.
This patch adds clk accuracy retrieval support for common clk framework by
means of a new function called clk_get_accuracy.
This function returns the given clock accuracy expressed in ppb.
In order to get the clock accuracy, this implementation adds one callback
called recalc_accuracy to the clk_ops structure.
This callback is given the parent clock accuracy (if the clock is not a
root clock) and should recalculate the given clock accuracy.
This callback is optional and may be implemented if the clock is not
a perfect clock (accuracy != 0 ppb).

clk/zynq/clkc: Add 'fclk-enable' feature
In some use cases Zynq's FPGA clocks are used as static clock
generators for IP in the FPGA part of the SOC for which no Linux driver
exists and would control those clocks. To avoid automatic
gating of these clocks in such cases a new property - fclk-enable - is
added to the clock controller's DT description to accomodate such use
cases. It's value is a bitmask, where a set bit results in enabling
the corresponding FCLK through the clkc.
FPGA clocks are handled following the rules below:
If an FCLK is not enabled by bootloaders, that FCLK will be disabled in
Linux. Drivers can enable and control it through the CCF as usual.
If an FCLK is enabled by bootloaders AND the corresponding bit in the
'fclk-enable' DT property is set, that FCLK will be enabled by the clkc,
resulting in an off by one reference count for that clock. Ensuring it
will always be running.

If an error happens after creating the first one debugfs_remove() is

clk: tegra: Fix vde/2d/3d clock src offset
In Tegra114, vde/gr_2d/gr_3d have 3 bits for clock source selection.
So change the clock init macro for these clocks from
"TEGRA_INIT_DATA_INT" to "TEGRA_INIT_DATA_INT8".
Besides, no one uses "TEGRA_INIT_DATA_INT" after this change, so
remove this macro.

This commit introduces a new group of clocks present in Armada 370/XP
SoCs (called "Core Divider" clocks) and add a provider for them.
The only clock supported for now is the NAND clock (ndclk), but the
infrastructure to add the rest is already set.
