This patch fixes most of the sparse endianness warnings in stm32.
The patch itself doesn't change anything apart from markings,
but there is some questionable code in stm32_cryp_check_ctr_counter.
That function operates on the counters as if they're in CPU order,
however, they're then written out as big-endian. This looks like
a genuine bug. Therefore I've left that warning alone until
someone can confirm that this really does work as intended on
little-endian.

pm_runtime_get_sync() increments the runtime PM usage counter
even when it returns an error code. However, users of cc_pm_get(),

on the error handling path to keep the counter balanced.

This patch squashes all the sparse warnings in mediatek, some of
which appear to be genuine bugs. In particular, previously on
BE the keys and IVs all get 32-bit swabbed which can't be right
because they don't get swabbed on LE. I presume LE is the one
that actually works.
Another funky thing is that the GHASH key gets swabbed on LE.
This makes no sense but I'm presuming someone actually tested
this on LE so I'm preserving the swabbing. Someone needs to
test this though as it is entirely possible that GCM is the
only thing that worked on BE but not LE.

When the devices are removed or not existing, the corresponding algorithms
which are registered by 'hisi-zip' driver can't be used.
Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to
'hisi_zip_probe'. The algorithms will be registered to crypto only when
there is device bind on the driver. And when the devices are removed,
the algorithms will be unregistered.
In the previous process, the function 'xxx_register_to_crypto' need a lock
and a static variable to judge if the registration is the first time.
