AT91: atmel_pwm only available for certain AT91 processors

Only three of Atmel's AT91 processors (SAM9263, SAM9RL and CAP9)
include a PWM controller.
It should therefore only be possible to enable the misc/atmel_pwm.c
driver on those processors (and not all AT91 processors).

This option enables device driver support for the PWM channels
on certain Atmel prcoessors. Pulse Width Modulation is used for
