layout: Tidy up forward declarations

* Parameter names like `flashctx` for a `struct flashrom_flashctx`
  don't add any value.
* `const` qualification of parameters is meaningless in forward
  declarations. Arguments are always passed by copy and an API
  user does not need to know what callees do with their copy.
