RTC: Prevents a division by zero in kernel code.
This patch prevents a user space program from calling the RTC_IRQP_SET
ioctl with a negative value of frequency. Also, if this call is make
with a zero value of frequency, there would be a division by zero in the
kernel code.
[jstultz: Also initialize irq_freq to 1 to catch other divbyzero issues]
