Add a rudimentary PWM driver for the RaspberryPi. Control is through sysctl, only GPIO12 supported. bootverbose creates sysctls for direct mangling of relevant registers. Only tested on RPI2 2018-01-14 20:36:21 +00:00			`# $FreeBSD$`

Rename rpi_pwm to bcm283x_pwm, and build it on armv[67] and arm64. Truncate ratio if period is lowered. Tested on Rpi2 and Rpi3. Rpi3 requires DTB->DTS->edit->DTB hack 2018-01-21 21:27:41 +00:00			`KMOD= bcm283x_pwm`
