ASoC: davinci-mcasp: HACK interface to handle dra7-evm's i2c2/HDMI mux

McASP2_ACLKR pin (in McASP8.AXR2 mode) is used in GPIO mode to control
the mux selection between I2C2 or HDMI.
This patch adds direct interface to handle this:
dra7_mcasp_hdmi_gpio_get() to select GPIO mode with pm_runtime_get
dra7_mcasp_hdmi_gpio_set() to change the GPIO pin state
dra7_mcasp_hdmi_gpio_put() to disable the GPIO mode and pm_runtime_put
