pinctrl: baytrail: Add pinconf group + function for the pmu_clk
On the Lenovo Yoga Tablet 2 830 / 1050 / 1051 models the 32KHz PMU clk, which can be muxed externally to SUS pin 5 and/or 6 is used as a clock for the audio codec. On the 830 and 1050 models, with ship with Android as factory OS the pin-muxing for this is not setup by the BIOS. Add a pinconf group + function for the pmu_clk on SUS pin 5 and 6 to allow setting the pinmux up from within the x86-android-tablets platform code.
