Subject: [PATCH] Rename pwm_devinit() to board_pwm_setup().  Add
 CONFIG_BOARDCTL_PWMTEST that will enable calling board_pwm_setup() from
 boardctl().  Replace calls to pwm_devinit() in apps/examples/pwm with calls
 to boardctl().  In all configurations that enable the apps/examples/pwm test,
 make sure that boardctl() suppoprt is properly enabled.
