<generated/at91_pm_data-offsets.h> is only generated and included
by arch/arm/mach-at91/, so it does not need to reside in the
globally visible include/generated/.

I moved and renamed it to arch/arm/mach-at91/pm_data-offsets.h
since the prefix 'at91_' is just redundant in mach-at91/.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Can this be applied to ARM-SOC tree in a series?
(with Ack from the platform sub-maintainer.)

at91_pm_data-offsets.h header does not need to reside in
include/generated/, but you may ask
"Why must it get out of include/generated/?"

My main motivation is to avoid a race condition in the currently
proposed patch:

https://lore.kernel.org/patchwork/patch/1052763/

This patch tries to embed some build artifacts into the kernel.

If arch/arm/mach-at91/ and kernel/ are built at the same time,
it may embed a truncated file.

Applied in at91-soc. Let me know if it's an issue, I plan to do the PR
soon.

There is one minor issue.

If you apply 2/3 (this one) alone,
arch/arm/mach-at91/pm_data-offsets.h is not cleaned.


1/3 fixes the "make clean" issue:
https://lkml.org/lkml/2019/4/8/153


That is why I sent this as a series
in order to avoid the regression of cleaning.



Thanks.

Sorry. A more fatal issue is this breaks O= build.

Could you drop it?
