Subject: [PATCH v4 8/9] ASoC: atmel-classd: remove aclk clock
Since gclk (generated-clk) is now able to determine the rate of the
audio_pll, there is no need for classd to have a direct phandle to the
audio_pll while already having a phandle to gclk.
Thus, remove all mentions to aclk in classd driver and update macros and
variable names.
