The following UBSAN error is reported during boot on the db410c board on
a clang-19 build:
Internal error: UBSAN: array index out of bounds: 00000000f2005512 [#1] PREEMPT SMP
...

The cause of the error is that the counter member was not set before
accessing the annotated flexible array member, but after that. Fix this
by initializing it earlier.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/interconnect to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

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.

The downstream kernel has infrastructure for passing votes from different
interconnect nodes onto different RPMh RSCs. This neither implemented, not
is going to be implemented upstream (in favor of a different solution
using ICC tags through the same node).
Unfortunately, as it happens, meaningless (in the upstream context) parts
of the vendor driver were copied, ending up causing havoc - since all
"per-RSC" (in quotes because they all point to the main APPS one) BCMs
defined within the driver overwrite the value in RPMh on every
aggregation.
To both avoid keeping bogus code around and possibly introducing
impossible-to-track-down bugs (busses shutting down for no reason), get
rid of the duplicated BCMs and their associated ICC nodes.
