target: align switch and case statements

The coding style requires the 'case' to be at the same indentation
level of its 'switch' statement.

Align the code accordingly.

While there:
- add space around the operators;
- drop useless empty line.

Skip all riscv code, as it is going to be updated soon from the
external fork.

No changes are reported by
	git log -p -w --ignore-blank-lines --patience
