xtensa: Partially Revert "xtensa: Remove unnecessary of_platform_populate with default match table"

This partially reverts commit 69d99e6c keeping only the main
purpose of the original commit which is the removal of
of_platform_populate() call. The moving of of_clk_init() caused changes
in the initialization order breaking booting.
