Make it possible to ask the routines used for adding/removing devices

devices so that they are put into the full-power state automatically
by acpi_dev_pm_attach() and into the lowest-power state available
automatically by acpi_dev_pm_detach().

platform / ACPI: Attach/detach ACPI PM during probe/remove/shutdown

Drivers usually expect that the devices they are supposed to handle
will be operational when their .probe() routines are called, but that
need not be the case on some ACPI-based systems with ACPI-based
device enumeration where the BIOSes don't put devices into D0 by
default.  To work around this problem it is sufficient to change
bus type .probe() routines to ensure that devices will be powered
on before the drivers' .probe() routines run (and their .remove()
and .shutdown() routines accordingly).

Modify platform_drv_probe() to run acpi_dev_pm_attach() for devices
whose ACPI handles are present, so that ACPI power management is used
to change their power states.  Analogously, modify
platform_drv_remove() and platform_drv_shutdown() to call
acpi_dev_pm_detach() for those devices, so that they are not subject
to ACPI PM any more.

spi / ACPI: add ACPI enumeration support

ACPI 5 introduced SPISerialBus resource that allows us to enumerate and
configure the SPI slave devices behind the SPI controller. This patch adds
support for this to the SPI core.

In addition we bind ACPI nodes to SPI devices. This makes it possible for
the slave drivers to get the ACPI handle for further configuration.
