crypto: jitter - set default OSR to 3
The user space Jitter RNG library uses the oversampling rate of 3 which
implies that each time stamp is credited with 1/3 bit of entropy. To
obtain 256 bits of entropy, 768 time stamps need to be sampled. The
increase in OSR is applied based on a report where the Jitter RNG is
used on a system exhibiting a challenging environment to collect
entropy.
This OSR default value is now applied to the Linux kernel version of
the Jitter RNG as well.
The increase in the OSR from 1 to 3 also implies that the Jitter RNG is
now slower by default.
