This commit updates the KMAC's register interface to match the latest
changes to Earlgrey's KMAC. These changes include:
- Removal of `ERR_PROCESSED` from the `CFG_SHADOWED` register.
- Addition of the `ERR_PROCESSED` command. Most of the functionality
is related to the entropy FSM which is still a TODO, but this does
also clear the relevant alert as in the RTL.
- Replaced `ENTROPY_SEED_{0,4}` with just one `ENTROPY_SEED` register,
which shifts the mappings of subsequent registers.
- Increase the MMIO State and MSG FIFO sizes.

kmac_smoketest, which still passes. It also makes the following tests (which were previously failing) pass:kmac_functest,kmac_functest_hardcoded,kmac_mode_cshake_testandkmac_mode_kmac_test. All tests were built from master on OpenTitan.
