It was a bad idea to have composite clock directly managing gates.
All clocks drivers have been rewrite to not use this functionality
and directly export the gate. We can now remove this code.

- All used clocks are now exported.
- Use the macros from rk_cru.h so code is similar to other rk clock drivers.

The binding says that we can have one or two clocks to export.
The first one is the actual sdclock while the second is the sample clock.
Both have the same parent, clk_xin.
Correctly export the clocks for RK3399 and ZynqMP.
No need to use a high ID as before, we have our own clock domain so use
ids starting at 1 as all exported clocks should be.

When building the frequencies table we convert the value in the DTS to
megahertz and loose precision. While it's not a problem for most of the
DTS it is when the expected frequency value is strict down to the hertz.
So it's either we don't truncate the value and have some ugly and long
values in the sysctls or we just find the closest frequency.
Do the latter.

Using the effective group and not the real one when testing membership
has the consequence that unprivileged processes cannot see setuid
commands they launch until these have relinquished their privileges.
This is also in contradiction with how the similar cr_canseeotheruids()
works, i.e., by taking into account real user IDs.
Fix this by substituting groupmember() with realgroupmember(). While
here, simplify the code.

Use priv_check_cred() with a new privilege (PRIV_SEEJAILPROC) instead of
explicitly testing for UID 0 (the former has been the rule for almost 20
years).
As a consequence, cr_canseejailproc() now abides by the
'security.bsd.suser_enabled' sysctl and MAC policies.
Update the MAC policies Biba and LOMAC, and prison_priv_check() so that
they don't deny this privilege. This preserves the existing behavior
(the 'root' user is not restricted, even when jailed, unless
'security.bsd.suser_enabled' is not 0) and is consistent with what is
done for the related policies/privileges (PRIV_SEEOTHERGIDS,
PRIV_SEEOTHERUIDS).

3. net.inet.sctp.chunkscale
The loader tunable 'net.inet.sctp.tcbhashsize' and 'net.inet.sctp.chunkscale'
are only used during vnet initializing, thus it make no senses to make them
writable tunable.
Validate the values of loader tunables on vnet initialize, reset them to
theirs defaults if invalid to prevent potential kernel panics.
