of/platform: Unconditionally pause/resume sync state during kernel init
Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init and of_platform_populate()") paused/resumed sync state during init only if Linux had parsed and populated a devicetree. However, the check for that (of_have_populated_dt()) can change after of_platform_default_populate_init() executes. One example of this is when devicetree unittests are enabled. This causes an unmatched pause/resume of sync state. To avoid this, just unconditionally pause/resume sync state during init.
