ene_lpc.c: Move register_shutdown to the end of initialisation

A bit more details: since register_shutdown has moved a few lines
below, now ene_enter_flash_mode is called before the shutdown function
is registered. ene_enter_flash_mode can fail (at least in theory,
it has some return 1s), but its return value is not analyzed, so even if
it returns non-0, execution goes further and register_shutdown will
happen anyway.

It is a separate question whether the return value of
ene_enter_flash_mode needs to be analyzed or is it ok to ignore it,
but in this patch I plan to keep the same behaviour, and probably I
will get back to error handling later.

This unlocks API change which plans to move register_shutdown inside
register master API, see https://review.coreboot.org/c/flashrom/+/51761
