driver core: Provide device_match_acpi_handle() helper 

mainline inclusion
from mainline-v5.16-rc1
commit a164ff53
category: cleanup
bugzilla: https://gitee.com/openeuler/kernel/issues/I9QV07

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a164ff53cbd34479aeac3366840669b10845ce53



----------------------------------------------------------------------------

We have a couple of users of this helper, make it available for them.

The prototype for the helper is specifically crafted in order to be
easily used with bus_find_device() call. That's why its location is
in the driver core rather than ACPI.
