xtensa: Partially Revert "xtensa: Remove unnecessary of_platform_populate with defaul...

This partially reverts commit 69d99e6c0d62 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.

Fixes: 69d99e6c0d621f ("xtensa: Remove unnecessary of_platform_populate with default match table")
