clk: Allow clock defaults to be set during re-reloc state for SPL only

In commit e5e06b65ad65 ("clk: Allow clock defaults to be set also
during re-reloc state") the earlier guard against setting clock
defaults in pre-reloc state was removed. While it is easy to filter
'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS,
no such mechanism exists for the pre-reloc stage of the full U-Boot.

With the default defconfig for the RK3399-Q7 (which filter the
'assigned-clocks' property for the DTS used by SPL anyway), this
caused a pause during startup of the full U-Boot stage that lasted for
almost 10s (due to the CPU not having been clocked up yet).

This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow
clock defaults to be set also during re-reloc state") and extends it
to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will
now run in pre-reloc state for SPL, but only after reloc for the full
U-Boot.

The earlier commit f4fcba5c5ba ("clk: implement clk_set_defaults()")

rates and parents will skip the processing when executing in a re-reloc
state. This for example can prevent the assigning of clock parents
when running in SPL code. Go ahead and remove this limitation.

clk: clk_set_default: accept no-op skip fields

The Assigned Clock parents and rates misses the fact that a "0" entry can
be passed to skip setting a parent or rate of an assigned clock as
described in the Linux clock bindings at [1].

This patch simply skips the clock reparenting if the DT parsing returns
-ENOENT and the clock rate setting if "0" is passed as clock rate.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

clk: implement clk_set_defaults()

Linux uses the properties 'assigned-clocks', 'assigned-clock-parents'
and 'assigned-clock-rates' to configure the clock subsystem for use
with various peripheral nodes.

This implements clk_set_defaults() and hooks it up with the general
device probibin in drivers/core/device.c: when a new device is probed,
clk_set_defaults() will be called for it and will process the
properties mentioned above.

Note that this functionality is designed to fail gracefully (i.e. if a
clock-driver does not implement set_parent(), we simply accept this
and ignore the error) as not to break existing board-support.

For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS. This adds the required
plumbing and implements the GMAC case for the RK3399.

The logic in clk_get_by_index() may be useful for other properties

follows the same model.

This commit refactors clk_get_by_index() by introducing an internal
function clk_get_by_indexed_prop() that allows to specify the name
of the property to process. The original clk_get_by_index() call
is simply directed through this helper function with the property
name fixed to "clocks".
