Due to timing requirements, TI and Conexant manage the audio reference clock from their ASoC codec drivers using the "mclk" string. This patch adds a default alias to "pmc_plt_clk_3" to avoid Intel-specific tests in those codec drivers and use code as-is. "pmc_plt_clk_3" is used exclusively for audio on all known Baytrail/CherryTrail designs and is e.g. routed on the MCLK (pin 26) of the MinnowBoardMAX Turbot LSE connector.

Notes: This patch only applies on top of linux-next or clk-next, the previous clk-related patches are not yet merged in the audio trees
