7aefb47 jitterentropy-rngd: update to the v1.2.0
What's interesting about jitterentropy-rngd v1.2.0 release is that it
bumps its copy of jitterentropy-library from v2.2.0 to the v3.0.0. That
bump includes a relevant commit 3130cd9 ("replace LSFR with SHA-3 256").
When initializing entropy jent calculates time delta. Time values are
obtained using clock_gettime() + CLOCK_REALTIME. There is no guarantee
from CLOCK_REALTIME of unique values and slow devices often return
duplicated ones.
A switch from jent_lfsr_time() to jent_hash_time() resulted in many less
cases of zero delta and avoids ECOARSETIME.
Long story short: on some system this fixes:
[ 6.722725] urngd: jent-rng init failed, err: 2
This is important change for BCM53573 which doesn't include hwrng and
seems to have arch_timer running at 36,8 Hz.

Also the other type is worng and causes compile problems on ARM64
platforms.

GCC 9.1 complains about this wrong type used in the format string, fix
this to make the compiler happy.

μrngd is OpenWrt's micro non-physical true random number generator based
on timing jitter.
Using the Jitter RNG core, the rngd provides an entropy source that
feeds into the Linux /dev/random device if its entropy runs low. It
updates the /dev/random entropy estimator such that the newly provided
entropy unblocks /dev/random.
The seeding of /dev/random also ensures that /dev/urandom benefits from
entropy. Especially during boot time, when the entropy of Linux is low,
the Jitter RNGd provides a source of sufficient entropy.
