ACPI: Fix a hard coding style when determining if a device is a container, v3

"ACPI0004","PNP0A05" and "PNP0A06" are all defined in array
container_device_ids[], so use it, but not the hard coding style.

Also, introduce a new API is_container_device() to determine if a
device is a container device.

ACPI: Fix stale pointer access to flags.lockable

During hot-remove, acpi_bus_hot_remove_device() calls ACPI _LCK
method when device->flags.lockable is set. However, this device
pointer is stale since the target acpi_device object has been
already kfree'd by acpi_bus_trim().

The flags.lockable indicates whether or not this ACPI object
implements _LCK method. Fix the stable pointer access by replacing
it with acpi_get_handle() to check if _LCK is implemented.

ACPI: Remove unused lockable in acpi_device_flags

Removed lockable in struct acpi_device_flags since it is no
longer used by any code. acpi_bus_hot_remove_device() cannot
use this flag because acpi_bus_trim() frees up its acpi_device
object. Furthermore, the dock driver calls _LCK method without
using this lockable flag.

ACPI / Sleep: add acpi_sleep=nonvs_s3 parameter

The ACPI specificiation would like us to save NVS at hibernation time,
but makes no mention of saving NVS over S3.  Not all versions of
Windows do this either, and it is clear that not all machines need NVS
saved/restored over S3.  Allow the user to improve their suspend/resume
time by disabling the NVS save/restore at S3 time, but continue to do
the NVS save/restore for S4 as specified.

ACPI: move acpi_no_s4_hw_signature() declaration into #ifdef CONFIG_HIBERNATION

acpi_no_s4_hw_signature is defined in #ifdef CONFIG_HIBERNATION block,
but the current code put the declaration in #ifdef CONFIG_PM_SLEEP block.

I happened to meet this issue when I turned off PM_SLEEP config manually:
arch/x86/kernel/acpi/sleep.c:100:4: error: implicit declaration of function ‘acpi_no_s4_hw_signature’ [-Werror=implicit-function-declaration]

ACPI / PM: Fix device PM kernedoc comments and #ifdefs

The kerneldoc comments for acpi_pm_device_sleep_state(),
acpi_pm_device_run_wake(), and acpi_pm_device_sleep_wake() are
outdated or otherwise inaccurate and/or don't follow the common
kerneldoc patterns, so fix them.

Additionally, notice that acpi_pm_device_run_wake() should be under
CONFIG_PM_RUNTIME rather than under CONFIG_PM_SLEEP, so fix that too.
