clk: sunxi-ng: Add sigma-delta modulation support

Sigma-delta modulation is supported for some PLLs. This allows
fractional-N multipliers to be used. In reality we don't know
how to configure the individual settings for it. However we can
copy existing settings from the vendor kernel to support clock
rates that cannot be generated from integer factors, but are
really desired. The vendor kernel only uses this for the audio
PLL clock, and only on the latest chips.

This patch adds a new class of clocks, along with helper functions.
It is intended to be merged into N-M-factor style clocks as a
feature, much like fractional clocks.

perf-help(1)
============

NAME
----
perf-help - display help information about perf

SYNOPSIS
--------
'perf help' [-a|--all] [COMMAND]

DESCRIPTION
-----------

With no options and no COMMAND given, the synopsis of the 'perf'
command and a list of the most commonly used perf commands are printed
on the standard output.

If the option '--all' or '-a' is given, then all available commands are
printed on the standard output.

If a perf command is named, a manual page for that command is brought
up. The 'man' program is used by default for this purpose, but this
can be overridden by other options or configuration variables.

Note that `perf --help ...` is identical to `perf help ...` because the
former is internally converted into the latter.

OPTIONS
-------
-a::
--all::
	Prints all the available commands on the standard output. This
	option supersedes any other option.
