Joel Stanley df563c85de gpio: aspeed: Don't attempt to debounce if disabled ...

We warn the user at driver probe time that debouncing is disabled.
However, if they request debouncing later on we print a confusing error
message:

 gpio_aspeed 1e780000.gpio: Failed to convert 5000us to cycles at 0Hz: -524

Instead bail out when the clock is not present.

Fixes: 5ae4cb94b3 (gpio: aspeed: Add debounce support)
