Subject: [PATCH] acpi: Remove unneeded nested #ifdef

In commit 5de21bb998b8 ("ACPI / PM: Drop CONFIG_PM_RUNTIME from the
ACPI core"), all occurrences of CONFIG_PM_RUNTIME were replaced with
CONFIG_PM. This created the following structure of #ifdef blocks in
the code:

[...]
#ifdef CONFIG_PM
#ifdef CONFIG_PM
/* always on / undead */
#ifdef CONFIG_PM_SLEEP
[...]
#endif
#endif
[...]
#endif

This patch removes the inner "#ifdef CONFIG_PM" block as it will
always be enabled when the outer block is enabled. This inconsistency
was found using the undertaker-checkpatch tool.
