Update the nrf51 and 52833 HAL since nrf-hal made a release.
Note that since we are pulling in a git version of nrf52833 HAL at the
moment the build is in fact broken without this PR.
Also since the HALs made a release now maybe it's time to make a
release here as well? That way I could also remove the git dependencies
from the discovery book so the build is more stable and doesn't break because
of stuff like this in the future.
