drivers/pinctrl/intel/pinctrl-baytrail.c: fix build with gcc-4.4

gcc-4.4 and thereabouts has issues with initializers of anonymous
unions, and it generates the following warnings:

drivers/pinctrl/intel/pinctrl-baytrail.c:413: error: unknown field 'simple_funcs' specified in initializer
drivers/pinctrl/intel/pinctrl-baytrail.c:413: warning: missing braces around initializer
drivers/pinctrl/intel/pinctrl-baytrail.c:413: warning: (near initialization for 'byt_score_groups[0].<anonymous>')
drivers/pinctrl/intel/pinctrl-baytrail.c:415: error: unknown field 'simple_funcs' specified in initializer
drivers/pinctrl/intel/pinctrl-baytrail.c:417: error: unknown field 'simple_funcs' specified in initializer
...

Work around this.
