spherion: config PWM KB backlight control
Move asurada baseboard PWM channels definition to board control.
Config gpio keyboard backlight en pin, and enable/disable
in power on/off sequence
BUG=b:181799718
BRANCH=none
TEST=make buildall
TEST=run 'kblight' EC console command to verify keyboard backight
TEST=run 'ectool verify pwmsetkblight' to verify keyboard backlight
