dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()

Currently the comments of several APIs (eg: dm_init_and_scan()) say:

@pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC
flag. If false bind all drivers.

The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt
documents the same that both device tree properties and driver flag
are supported.

However the implementation only checks these special device tree
properties without checking the driver flag at all. This updates
lists_bind_fdt() to consider both scenarios.

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.

dm: timer: handle being called before dm_root is ready

When used with bootstage recording, dm_timer_init may be called
surprisingly early: i.e. before dm_root is ready. To deal with
this case, we explicitly check for this condition and return
-EAGAIN to the caller (refer to drivers/timer/rockchip_timer.c
for a case where this is needed/used).

The timer-uclass depends on full OF_CONTROL through its interrogation

For the OF_PLATDATA case, these code-paths are disabled and it becomes
the timer driver's responsibility to correctly set the clock-frequency
in the uclass priv-data.

timer: Support clocks via phandle

Earlier timer driver needed a clock-frequency property in compatible
device-tree nodes. Another way is to reference a clock via a phandle.

So now timer_pre_probe tries to get clock by reference through device
tree. In case it is impossible to get clock device through the
reference, clock-frequency property of the timer node is read to provide
backward compatibility.
