The SAM0 has a data register and a shift register. Data that is
written to the data register is transferred to the shift register by
the peripheral.
On the SAMD51, the CPU is fast enough that the first data write hasn't
been transferred to the shift register by the time the next data write
occurs, causing the second write to be dropped, causing the receiver
to wait forever.
Fix by spinning until the data register is empty.

The possibility of passing K_FOREVER as the initial duration argument
to k_timer_start() wasn't being handled, with the result that the
computed value became an zero timeout (effecitvely treating it as
K_NO_WAIT and firing at the next tick).
This is obviously pathlogical, but it should still do what the code
says it should and wait forever.
Make k_timer_start(..., K_FOREVER, ...) a noop.

The bt_l2cap_le_conn_rsp struct in l2cap_internal.h has not been
declared __packed. This can cause alignment problems on some
platforms if the struct is placed on an unaligned address.
A __packed declaration solves this issue by forcing the compiler to
use store instructions that do not required alignment.

Some kernel tests use `CONFIG_TICKLESS_KERNEL=n` with

The commit a8e90cbfb3 improved handling of
shields. Unfortunately it pops items from the SHIELD variable which
works well if SHIELD is a CMake ;-separated list, but if the list is
a space separated list, as may be provided by the user, then this
principle fails as reported in #25656.
This is fixed by keeping improved behaviour, while popping from an
alternative SHIELD-NOTFOUND list instead.

Add test cases that verify various bits and pieces of the legacy
devicetree macros match the new APIs.
Writing these test cases without giving rise to deprecated macro
warnings which might break people's CI if they build with -Werror
requires turning off the __WARN() generation in
devicetree_legacy_unfixed.h. The entire file is deprecated at this
point and must be explicitly enabled with an opt-in Kconfig option, so
there isn't any harm in doing this.
Nevertheless, take a minimally invasive approach to avoiding __WARN()
generation in gen_legacy_defines.py, to avoid the possibility of
breakage. This code is basically frozen anyway, so hacks like this
won't cause maintainability problems since it isn't being actively
maintained.
Use the new tests as fodder for a migration guide from the old API in
the documentation.
