00a973e093 interconnect: qcom: icc-rpm: Set the count member before accessing the flex array 
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
...
pc : qnoc_probe+0x5f8/0x5fc
...

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.

31f1b03fbd interconnect: Switch back to struct platform_driver::remove() 
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.
