Skip restyling of PSA error code definitions

Some preprocessor macro definitions must have a specific expansion so that
the same macro name can be defined in different products. The definition of
having the same expansion (per the C language specification) means the same
sequence of tokens, and also the same absence/presence of spacing between
tokens.

For PSA error code definitions, the specific expansion is mandated by the
PSA Status code specification and the PSA Crypto API specification. In
particular, there must not be a space between (psa_status_t) and the
numerical value (whereas K&R would put a space).
