cfi_flash: Add interface for flash verbosity control

Browse Source 
Add interface for flash verbosity control. It allows
to disable output from low-level flash API. It is useful
when calling these low-level functions from context other
than flash commands (for example the MTD/CFI interface
implmentation).
