[coreboot-gerrit] Change in coreboot[master]: nb/intel/sandybridge: Introduce `iosav_run_once_and_wait`

[Angel Pons (Code Review)]

Hello  Felix Singer, build bot (Jenkins), Nico Huber, Patrick Georgi, Arthur Heymans, Patrick Rudolph, Felix Held,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).

nb/intel/sandybridge: Introduce `iosav_run_once_and_wait`

Most ofte, `iosav_run_once` precedes a `wait_for_iosav` call. Add a
helper function to reduce clutter. The cases where `iosav_run_once`
isn't followed by `wait_for_iosav` will be handled in a follow-up.

Tested on Asus P8Z77-V LX2, still boots.
