software, integration/export: (re-)expose CSR subregister accessors

Expose a pair of `csr_[read|write]_simple()` subregister accessors, and
restore the way dedicated accessors are generated in "generated/csr.h"
to use hard-coded combinations of shifts and subregister accessor calls.

This restores downstream ability to override CSR handling at the
subregister accessor level.
