video: fbdev: sstfb: Updated logging to fix set but not used warnings

Fix set but not used warnings by introducing no_printk variants
for the internal logging system for this driver.

Fix a new warning that popped up now that logging was checked for
correct printf format strings.

A more invasive fix had been to replace all the internal logging with
standard logging primitives - thats for another day.

v2:
- Update subject (Lee)
