compiler*.h: sync include/linux/compiler*.h with Linux 5.7-rc5

Copy these from Linux v5.7-rc5 tag.

This brings in some handy new attributes and is otherwise important to
keep in sync.

We drop the reference to smp_read_barrier_depends() as it is not
relevant on the architectures we support at this time, based on where
it's implemented in Linux today.  We drop the call to kasan_check_read()
as that is not relevant to U-Boot as well.
