soc: fsl: cpm1: qmc: Set the ret error code on platform_get_irq() failure

A kernel test robot detected a missing error code:
qmc.c:1942 qmc_probe() warn: missing error code 'ret'

Indeed, the error returned by platform_get_irq() is checked and the
operation is aborted in case of failure but the ret error code is
not set in that case.

Set the ret error code.

soc: fsl: cpm1: tsa: switch to for_each_available_child_of_node_scoped()

The non-scoped variant of this macro turns error-prone as soon as error
paths are included, because explicit calls to of_node_put() are required
to avoid leaking memory.

Using its scoped counterpart simplifies the code by removing the need of
explicit calls to of_node_put(), as they are automatically triggered as
soon as the child node goes out of scope. Moreover, it is more robust as
it accounts for new error paths without having to worry about
decrementing the object's refcount.

Note that the device_node is declared within the macro, and its explicit
declaration can be dropped as well if it is not used anywhere else.
