Add make scripts target. Yocto builds remove this.
Add script to setup up cross-compile with Yocto built tools
Use GPL for license. Inconsistent before between BSD in header and GPL in MODULE_LICENSE.
Run pwm.h through scripts/cleanfile
Add ioctl as alternative to write for changing duty cycle
Formatting, use tabs
Add irq_mode

In irq_mode only change TMAR inside of a MATCH interrupt handler.
Fixes improper behavior when the timer speed is modified at a high rate.
Allow speeds other then 50Hz for servo mode
Add watchdog timeout

If enabled then reset timer to minimum value if there have been
no speed updates in the timeout period.
Add environment script for Yocto built cross systems

Remove redundant yocto-cross-env.sh
PWM_PULSE_RESET in non-servo mode puts duty cycle to zero
added timeout reset to ioctl
