Fabio Estevam 54fe0791fa clk: imx7d: Add PLL_AUDIO_TEST_DIV/POST_DIV clocks
Currently we see the following error when using the SAI audio
driver on mx7:

Division by zero in kernel.
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.8.0-rc3-next-20160823
Hardware name: Freescale i.MX7 Dual (Device Tree)
Backtrace:

[<c06cd860>] (divider_get_val) from [<c06cda28>] (clk_divider_se)

This error happens due to the lack of definition of the
IMX7D_PLL_AUDIO_TEST_DIV/IMX7D_PLL_AUDIO_POST_DIV clocks.

Add support for them.

Tested on a imx7s-warp board.
