Change cfs_crypto_hash_final() to always clean up the hash descrptor
instead of not doing this in error cases.  All of the callers were
just calling cfs_crypto_hash_final() immediately to clean up the
descriptor anyway, and the old behaviour is unlike other init/fini
functions, and prone to memory leaks and other incorrect usage.  The
callers can call cfs_crypto_digest_size() to determine the hash size
in advance if needed, and avoid complexity in cfs_crypto_hash_final().

This function calls some helper functions to convert the counter variant
specific clock select bits into the generic enum ni_gpct_clock_source_bits
equivelent. These helper functions currently BUG() if the clock select
bits are invalid.

It then calls ni_tio_clock_period_ps() to figure out the clock period
based on the generic clock source. This function could also BUG() if
the prescale bits are invalid.

In reality this should never happen but refactor the code to return
-EINVAL instead and remove the BUG() checks.

These functions are also called by ni_tio_set_sync_mode(). When this
function is called by ni_tio_set_clock_src() the counter select bits
have already been validated.
