prandom: Include <linux/percpu.h> in <linux/prandom.h>
<linux/percpu.h> include was removed from <linux/prandom.h>
in d9f29deb7fe8 ("prandom: Remove unused include") because
this inclusion broke arm64 due to a circular dependency
on include files.
__percpu tag is defined in include/linux/compiler_types.h, so there
is currently no direct need for the inclusion of <linux/percpu.h>.
However, in [1] we would like to repurpose __percpu tag as a named
address space qualifier, where __percpu macro uses defines from
<linux/percpu.h>.
The circular dependency was removed in ddd8e37ebaa1 ("random: Do not
include <linux/prandom.h> in <linux/random.h>") and it cleared
the path for the inclusion of <linux/percpu.h> in <linux/prandom.h>.
This patch is basically a revert of d9f29deb7fe8
("prandom: Remove unused include").
