Implements get_line, so /proc/reset names all 324 lines and gives the
register and bit each lives in. The framework asks status() for the
asserted state.
The names do not survive compilation: they live in the enumeration, so
without a table a listing gives only numbers, and working back from one
to a peripheral means counting through the header. The table costs
about 8 KiB and is built only when the procfs entry is.
The ids are sparse, 324 lines across a space of 1952, so the table is
sorted by id and searched rather than indexed, and an id naming no line
returns -ENODEV. The framework skips those, which is what leaves the
listing dense.
