[U-Boot] [PATCH v4 08/16] Define board_quiesce_devices() in a shared location

[Simon Glass <sjg@chromium.org>]

This undocumented function relies on arch-specific code to declare a nop
weak version. Add the weak function in common code instead to avoid having
to duplicate the same function in each arch.
