[PATCH 00/23] component: Add common helpers for compare/release

[Yong Wu]

The component requires the compare/release functions, there are many
copies in current kernel. This patchset just defines four common helpers
for them. No functional change.

Change note:
v1: a) Split the original patch into many small patches.
    b) Use device_match_of_node helper.
    c) Move the functions into c and export since
    the callback doesn't look like it should be "inline".
    d) Add "component_" prefix for the functon names.
    e) Add a new component_compare_dev_name.

    rebase on v5.17-rc1
