           Summary: pinctrl_cherryview module will freeze intel NUC5CPYH

dmesg output

If CONFIG_PINCTRL_CHERRYVIEW=m is enabled in config, intel NUC5CPYH (also
NUC5PPYH tested, same thing) will freeze on boot 9 out of 10 times. Also, after
succesful boot reboot will most likely fail, HDMI will turn of and hang there.

Workaround:  BIOS > Boot > Boot Configuration > OS Selection > set Linux

With above BIOS settings, it boots just fine and also reboot works.
