- the PeakRDL `c-header` plugin generates structs with `__attribute__((__packed__))` which ensures proper packing of fields but can also cause the compiler to emit byte loads/stores to access 32-bit registers, which is definitely not what we want. The `unpacked` version of the C header has the attribute removed. - The `idma_sw_clean` target had a typo and didn't actually clean anything, this is fixed now.

Therawversion is (with the current version ofraw-header) somewhat incomplete as the masks for sub-register bitfields have to be generated/hardcoded externally.deployCI job calls this target anddeploy.pyis amended to edit the appropriate.gitignore; C headers are also checked intodeploybranchesuv.lockandpyproject.tomlamended so thec-headerplugin is part of the environment
