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)

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.
