ACPI / MMC: PM: Unify fixing up device power
Introduce acpi_device_fix_up_power_extended() for fixing up power of
a device having an ACPI companion in a manner that takes the device's
children into account and make the MMC code use it in two places
instead of walking the list of the device ACPI companion's children
directly.
This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).
