Currently, the audio sampler clock is enabled from dw_hdmi_setup() at step E. and is kept enabled for later use. This clock should be enabled and disabled along with the actual audio stream and not always on (that is bad for PM). Furthermore, as described by the datasheet, the I2S variant needs to gate/ungate the clock when the stream is enabled/disabled. This commit adds a parameter to hdmi_audio_enable_clk() that controls when the audio sample clock must be enabled or disabled. Then, it adds the call to this function from dw_hdmi_i2s_audio_enable() and dw_hdmi_i2s_audio_disable().

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
