Add snps,pwm-number property to indicate if the block does not have
all 8 of the PWM blocks.

Not sure if this should be a general PWM property consider optional
for all PWM types, so have added a specific one here (there is only
one other controller with a property for PWM count at the moment)

1. No quotes
2. Add minimum and maximum (it looks like there are such).
