armv8: layerscape: rework spin table
There are two issues:
(1) The spin table doesn't convert the endianness of the jump address.
Although there is code for it, the result isn't used at all (x0).
(2) If something goes wrong, the function returns. But that doesn't
make sense at all.
Use the actual converted jump address as destination to fix. If
there is an error, jump to a trap loop. And rearrange the code exception
level switching code to make it smaller and clearer.
This reduces the size of the spin table code section from 696 bytes to
424 bytes. If CONFIG_ARMV8_SWITCH_TO_EL1 the code size reduced from 696
bytes to 632 bytes.

armv8: layerscape: fix spin-table support
Spin tables are broken with bootefi. This is because - in contrast to
the booti call chain - there is no call to smp_kick_all_cpus(). Due to
this missing call the secondary CPUs are never released from their "wait
for interrupt state", see secondary_boot_func() in lowlevel.S.
Originally, this "wait for interrupt" is there to make sure, the spin
table is cleared before the secondary cores read it for the first time.
But the boot flow for the layerscape architecture is different from
that. The CPUs are release from their BootROM _after_ U-Boot's
spin-table is cleared, see fsl_layerscape_wake_seconday_cores() in mp.c.
Thus, there is no need to wait for this interrupt and no need for
kicking all cores on cpu_release. An atomic 64bit write to the
spin-table and a "sev" is sufficient.

Timer capability is needed for both UP and SMP.

It also removes some quite ugly macros. Let's do the minimal revert

lib: crypto: export and enhance pkcs7_verify_one()
The function, pkcs7_verify_one(), will be utilized to rework signature
verification logic aiming to support intermediate certificates in
"chain of trust."
To do that, its function interface is expanded, adding an extra argument
which is expected to return the last certificate in trusted chain.
Then, this last one must further be verified with signature database, db
and/or dbx.
This function was nullified when the file, pkcs7_verify.c, was imported
because it calls further linux-specific interfaces inside, hence that
could lead to more files being imported from linux.
We need this function in pkcs7_verify_one() and so simply re-implement it
here instead of re-using the code.
The file, pkcs7_verify.c, will now be imported from linux code
(crypto/asymmetric_keys/pkcs7_verify.c in 5.7) and modified to fit
into U-Boot environment.
In particular, pkcs7_verify_one() function will be used in a later patch
to rework signature verification logic aiming to support intermediate
certificates in "chain of trust."
When the file, x509_public_key.c, was imported from linux code in
commit b4adf627d5b7 ("lib: crypto: add x509 parser"),
x509_check_for_self_signed() was commented out for simplicity.
Now it need be enabled in order to make pkcs7_verify_one(), which will be
imported in a later patch, functional.
This function will be called from x509_check_for_self_signed() and
pkcs7_verify_one(), which will be imported from linux in a later patch.
While it does exist in linux code and has a similar functionality of
rsa_verify(), it calls further linux-specific interfaces inside.
That could lead to more files being imported from linux.
So simply re-implement it here instead of re-using the code.
