cr50: update TRNG resets
It seems we have relatively high number of devices with slow TRNG,
mostly Octopus and Grunt platforms. To mitigate potential issues
increased TRNG reset counts from 8 to 16 to give a chance to recover,
and updated recording of TRNG stall to record only first occurrence
of stall per 32-bit.
BUG=b:211648605
TEST=test/tpm_test/nist_entropy.sh - loads TRNG
