printk: stop including cache.h from printk.h
An inclusion of cache.h in printk.h was added in 2014 in commit
c28aa1f0a847 ("printk/cache: mark printk_once test variable
__read_mostly") in order to bring in the definition of __read_mostly. The
usage of __read_mostly was later removed in commit 3ec25826ae33 ("printk:
Tie printk_once / printk_deferred_once into .data.once for reset") which
made the inclusion of cache.h unnecessary, so remove it.
We have a small amount of code that depended on the inclusion of cache.h
from printk.h; fix that code to include the appropriate header.
This fixes a circular inclusion on arm64 (linux/printk.h -> linux/cache.h
-> asm/cache.h -> linux/kasan-enabled.h -> linux/static_key.h ->
linux/jump_label.h -> linux/bug.h -> asm/bug.h -> linux/printk.h) that
would otherwise be introduced by the next patch.
Build tested using {allyesconfig,defconfig} x {arm64,x86_64}.
