When the dts file has multiple referrers to a single PD (e.g.
simple-framebuffer and dss nodes both point to the DSS power-domain) the
ti-sci driver will create two power domains, both with the same ID, and
that will cause problems as one of the power domains will hide the other
one.
Fix this checking if a PD with the ID has already been created, and only
create a PD for new IDs.
Fixes: efa5c01cd7ee ("soc: ti: ti_sci_pm_domains: switch to use multiple genpds instead of one")

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args. Make the argument
pointer to const for code safety and readability.

devm_kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.

for_each_node_with_property performs an of_node_get on
each iteration, so a break out of the loop requires an
of_node_put.
This was done using the Coccinelle semantic patch
iterators/for_each_child.cocci

The TI_SCI_PM_DOMAINS Kconfig option belongs closer to its corresponding
implementation, hence let's move it from the soc subsystem to the pmdomain
subsystem.
While at it, let's also add a Kconfig option the omap_prm driver, rather
than using ARCH_OMAP2PLUS directly.

It has been pointed out that naming a subsystem "genpd" isn't very
self-explanatory and the acronym itself that means Generic PM Domain, is
known only by a limited group of people.
In a way to improve the situation, let's rename the subsystem to pmdomain,
which ideally should indicate that this is about so called Power Domains or
"PM domains" as we often also use within the Linux Kernel terminology.
