superio/ite: Add full-speed config option
Add Kconfig option for full-speed setting. Some variants do not support
the full-speed at limit configuration (IT8772F). Keep it enabled for all
current variants that use the common EC code as it was previously
enabled unconditionally - datasheets weren't revisited individually.
