Some board designers, when running out of clock output pads, decide to
(mis)use PWM output pads to provide a clock to external components.
This driver supports this practice by providing an adapter between the
PWM and clock bindings in the device tree. As the PWM bindings specify
the period in the device tree, this is a fixed clock.

On dm816x the clocks are sourced from a FAPLL (Flying Adder PLL)
that does not seem to be used on the other omap variants.

There are four instances of the FAPLL on dm816x that each have three
to seven child synthesizers.

I've set up the FAPLL as a single fapll.c driver. Later on we could
potentially have the PLL code generic. To do that, we would have to
consider the following:

1. Setting the PLL to bypass mode also sets the child synthesizers
   into bypass mode. As the bypass rate can also be generated by
   the PLL in regular mode, there's no way for the child synthesizers
   to detect the bypass mode based on the parent clock rate.

2. The PLL registers control the power for each of the child
   syntheriser.

Note that the clocks are currently still missing the set_rate
implementation so things are still running based on the bootloader
values. That's OK for now as most of the outputs have dividers and
those can be set using the existing TI component clock code.

I have verified that the extclk rates are correct for a few clocks,
so adding the set_rate support should be fairly trivial later on.

This code is partially based on the TI81XX-LINUX-PSP-04.04.00.02
patches published at:

Some clock modules on the A31 use PLL6x2 as one of their inputs.
This patch changes the PLL6 implementation for A31 to a divs clock,
i.e. clock with multiple outputs that have different dividers.
The first output will be the normal PLL6 output, and the second
will be PLL6x2.

This patch fixes the PLL6 N factor in the clock driver, and removes
any /2 dividers in the PLL6 factors clock part. The N factor counts
from 1 to 32, mapping to values 0 to 31, as shown in the A31 manual.
