drivers: clk: remove spinlock in clk_print_tree()

Remove spinlock handling from clk_print_tree(). This lock may mask
interrupts for a long period of time which and may affect the system
behavior. Since there is no clock unregistering and clock destroying
function, all clock references used are safe to use, even outside
the locked state. Whether or not printed information is accurate is
not an issue as clk_print_tree() is concerned as the function is only
informative.

core: arm: Move some DT functions to common kernel

Some existed functions for device tree in ARM could be also used for
other architectures. This commit moves most of functions from ARM
architecture into "core/kernel/dt.c", including external DT descriptor,
DT overlay, external DT initialization, API for adding DT child nodes
and reserved-memory nodes. Since "core/kernel/dt.c" is dependent with
CFG_DT, other functions which are independent with CFG_DT are put into
new file "core/kernel/boot.c".

This change updates dt_driver.c, dt_driver.h and all drivers
implementing related dt_driver callback function.

As a consequence, this change removes all type definition related
to device specific callback handler function types which are useless
as all these now comply with type dt_driver_probe_func defined in
dt_driver.h.
