pwm: Add common initialization for PWM pins
Rather than having various PWM module groups initialized from various
HOOK_INIT functions, group them all into a single module and initialize
them all from a common function in pwm.c.
BUG=chromium:563708
TEST=Manual on samus / samus_pd (with CONFIG_ADC enabled). Verify that
samus fan + KB backlight control is functional and samus_pd correctly
sets PWM output.
BRANCH=None
