In case of error, the functions clk_register_composite() and
clk_register_divider() returns ERR_PTR() and never returns NULL.
The NULL test in the return value check should be replaced with
IS_ERR().

Contrary to what the datasheet says, the pre divider doesn't seem to be
incremented by one in the PLL2, but just uses the value from the register,
with 0 being a bypass.
This fixes the audio playing too fast.
Since we now have the same pre-divider flags, and the only difference with
the A10 is the post-divider offset, also remove the structure to just pass
the offset as an argument.

The A13, unlike the A10 and A20, doesn't use a pass-through exception for
the 0 value in the pre and post dividers, but increments all the values
written in the register by one.
Add an exception for both these cases to handle them nicely.

The PLL2 on the A10 and later SoCs is the clock used for all the audio
related operations.
This clock has a somewhat complex output tree, with three outputs (2X, 4X
and 8X) with a fixed divider from the base clock, and an output (1X) with a
post divider.
However, we can simplify things since the 1X divider can be fixed, and we
end up by having a base clock not exposed to any device (or at least
directly, since the 4X output doesn't have any divider), and 4 fixed
divider clocks that will be exposed.
This clock seems to have been introduced, at least in this form, in the
revision B of the A10, but we don't have any information on the clock used
on the revision A.
