mtd: cfi_cmdset_0002: Tone down warning messages about TopBottom CFI field
Accept values of 2-5 for TopBottom, where the newly-added 4 and 5 values
mean a uniform layout. It does indicate WP layout but we don't handle that.
Also don't say "broken" when swapping erase regions in a top-boot chip.
That got retrospectively documented in the spec.
