This makes life easier when calling e.g. `saul_reg_write()` with data stored in flash. As now the signatures for reading and writing differ (in that `const` qualifier only), `saul_notsup()` is split into `saul_write_notsup()` and `saul_read_notsup()`. However, one is implemented as a symbol alias of the other, so that ROM consumption remains unchanged.
