Richard Purdie ff525695f2 classes: Add SPDX license identifiers
As stated in our top level license files, the license is MIT unless
otherwise stated. Add SPDX identifers accordingly. Replace older
license statementa with the standardised syntax. Also drop "All
Rights Reserved" expression as it isn't used now, doesn't mean anything
and is confusing.
