[v4 24/24] clk_k210.c: Clean up how we handle nop

[Tom Rini <trini@konsulko.com>]

Now that sandbox has <asm/barrier.h> and defines nop() there we should
include that in our driver for clarity and then remove our local nop()
from <k210/pll.h>.

I can see that our ARM <asm/barriers.h> should be <asm/barrier.h> and
updated in a few other ways to match how the kernel is currently.  This
is not a big deal yet as this driver is only for sandbox for risc-v
