Kevin O'Connor fa85094cbb irq: Allow boards to define the return type of irq_save() 
The AVR wants a uint8_t return type for irq_save(), but other
architectures will generally prefer int.  Allow the board to configure
the size of the flag by introducing an irqstatus_t typedef.

Kevin O'Connor 9dd101c26f irq: Prefer irq_disable/enable instead of irq_save/restore in cmds/tasks 
Task and command handlers always run with irqs enabled, so it is not
necessary to save/restore the irq state when disabling irqs in these
handlers.

Kevin O'Connor 4fcf5a31f5 pwmcmds: Add Kconfig option to allow boards to disable hardware PWM commands 
Some boards may not support hardware based PWM.  Update the build so
that those commands do not need to be compiled if they are not
available.
